2:00 次世代バッテリーのロードマップ
Cosmin Laslau, PhD, Analyst, Lux Research Inc.
Next-generation battery technologies such as lithium-air, lithium-sulfur, and solid-state threaten to disrupt the growing $20 billion Li-ion market. However, advancing Li-ion itself will present a moving target, as high-voltage cathodes and improved anodes move the performance needle. Lux Research looked at transportation, consumer electronics, and military applications to assess cost, performance, and outlook, and built a roadmap to show which next-generation energy storage technologies have the best chance of adoption, in which applications, and when.

2:30 世界のリチウムイオン電池市場 - 充電か放電か
Vishal Sapru, Research Manager, Energy & Power Systems, Frost & Sullivan, Inc.
The presentation will focus on market opportunities for lithium-ion batteries, with an end-user focus on consumer, industrial, automotive, and renewable energy / grid storage applications. The presentation will highlight the impact of the hybrid and electric vehicle slowdown on the lithium-ion battery market, and its potential impact on the renewable/grid storage battery business. The presentation will focus on key challenges, drivers and restraints, potential market size, and trends, among others.

It will cover the automotive, stationary, consumer electronics and other markets. This presentation will reveal initial results of the tracker, including market sizing and forecasting for each major sub-market.

3:30 休憩および展示品/ポスター観賞

4:00 水性リチウムイオン電池の最近の進展
Haiyan Wang, PhD, Researcher, School of Chemistry and Chemical Engineering, Central South University, China
The aqueous lithium-ion battery (ALIB) has been demonstrated to be one of the most promising stationary power sources for sustainable energies such as wind and solar power. During the past decades, many efforts have been made to improve the performance of the aqueous lithium-ion battery. On the basis of our group's research, the latest advances in the exploration and development of battery systems and relative materials will be demonstrated.

4:30 バッテリー級LiOHを生産するためのプロセスの開発と最適化:水とエネルギー消費の最適化
Wilson Alavia, PhD, Researcher Center for Advanced Research in Lithium and Industrial Minerals-Celimin, Universidad de Antofagasta, Chile*
To satisfy the current and future energy demand in Chile, the government is investing in ERNC and energy storage technologies, and specifically in lithium battery technologies. The components of our lithium batteries are fabricated from LiOH, which is produced from Li2CO3. In this presentation we will discuss development and optimization of a process for fabrication of LiOH battery grade from Li2CO3 using the metallurgic process simulator Metsim.

5:00 リチウムイオン電池熱電気化学モデルと宇宙アプリケーション用軌道熱分析ソフトウェアとの結合
William Walker, Researcher, NASA Johnson Space Center
Lithium-ion batteries (LIBs) are replacing some of the Nickel Metal Hydride (NiMH) batteries on the International Space Station. Knowing that LIB efficiency and survivability are highly influenced by the effects of temperature, this study focused on coupling orbital-thermal analysis software, Thermal Desktop (TD) v5.5, with LIB thermo-electrochemical models representing the local heat generated during charge/discharge cycles. Before attempting complex orbital analyses, a simple sink temperature model needed development to determine the compatibility of the two techniques. LIB energy balance equations solved for local heating (Bernardi's equation) were used as the internal volumetric heat generation rate for native geometries in TD. The sink temperature, various environmental parameters, and thermophysical properties were based on those used in a previous study for the end of 1, 2, & 3 Coulomb (C) discharge cycles of a 185 Amp-Hour (Ah) capacity LIB. The TD model successfully replicated the temperature vs. depth of discharge (DoD) profiles and temperature ranges for all discharge and convection variations with minimal deviation. In this study, we successfully developed the capability of programming the logic of the variables and their relationship to DoD into TD. This coupled version of orbital thermal analysis software and thermo-electrochemical models provides a new generation of techniques for analyzing thermal performance of batteries in orbital-space environments.

9:00 輸送におけるリチウムイオン電池の展望
Ralph Brodd, PhD, President, Broddarp of Nevada
The talk will summarize the recent NRC publication "Transitions to Alternative Vehicles and Fuels." The time line for introduction and the main factors controlling the transitions electrified transportation will be discussed. The study included a comparison of fuel cell, battery powered and hybrid vehicles as well as alternative fuels, such as ethanol, etc.

9:30 高度バッテリー設計ツールボックス
Bor Yann Liaw, Hawaii Natural Energy Institute, University of Hawaii at Manoa
We have recently developed a mechanistic model as a battery design toolbox that can emulate “what if” scenarios to predict battery performance and life under various duty cycle requirements. Based on half-cell data, we can compose metrics for cell performance by matching electrode loading and loading ratio to construct different configurations for performance and life prediction. This unique capability will allow the user through simple design panel to estimate various “what if” criteria to design the cell with the performance and life in mind. The presentation will explain the approach and utility offered by this model and toolbox.

10:00 ワイヤレス電源によるリチウムイオン電池の充電
William von Novak, Principal Engineer, QUALCOMM
Wireless charging for portable devices is becoming more popular, with several competing technologies currently on the market. Each has its drawbacks and benefits, and each presents different challenges for charging of lithium ion batteries. Tightly coupled technologies are highly efficient but tend to concentrate heat dissipation in the area near the battery; loosely coupled technologies are less efficient overall but result in more distributed heating. In addition, integration of the battery with common PMIC's (power management IC's) and portable device chipsets presents design challenges to the power system designer, including issues during dead battery startup and charge termination. This talk will provide an overview of the various types of wireless charging, along with their relative benefits and drawbacks, and will present some specific test results for charging on a loosely coupled (A4WP compliant) system. It will also present some general guidelines for designing wireless power systems to be compatible with lithium ion battery systems.

11:30 マイクロファイバー/ナノファイバーバッテリー分離器
Brian Morin, President and COO, Dreamweaver International
Current stretched porous film battery separators for lithium ion batteries are thin, strong, and provide a good barrier between electrodes, at the cost of having very high internal resistance and low ionic flow. In this work, linear nanofibers and microfibers are combined in wet laid nonwoven processes to give separators that are strong and thin, but have higher porosity (60%) and much higher ionic flow. Batteries made with these separators are able to give similar performance at much higher electrode coat weights, reducing the surface area of both current collectors and separator and also the volume of electrolyte needed. Total mass reduction can be as high as 20% (1.3 kg/kWh), with raw material cost savings of over 25% ($55/kWh). Volume savings are 0.5 liters/kWh. Batteries made with similar construction show much higher charge and discharge rate capability. Temperature stability is also improved, from a current stability temperature of about 110ËšC up to 175ËšC. Applications include all power source applications that require high energy density, high power, high temperature stability, including cell phones, laptop and tablet computers, power tools, and electric and hybrid vehicles.

12:00 新たな熱測定を通じたリチウムイオン電池形成プロセスの開発
Jeff Xu, PhD, Principal Scientist, Powertrain Controls, Engine & Vehicle R&D Department Southwest Research Institute
An important step often overlooked or rarely investigated in lithium-ion battery manufacturing is the formation process. The formation process is the first full charging cycle of a lithium ion battery, which activates the cells before the lithium-ion cells can be used. The presentation will focus using novel thermal measurement tool to monitor heat profile during the first charging/discharging cycle of new cells. The novel formation protocol can thus be developed to determine the impact of the Lithium-ion battery formation process on battery performance such as capacity, cycle life, and safety.

12:30 昼食

2:00 リチウムイオン電池用高出力高エネルギー変換電極の発見
Steven Kaye, PhD, Chief Scientific Officer, Wildcat Discovery Technology
Wildcat Discovery Technologies has developed a high throughput synthesis and screening platform for battery materials. Wildcat's system produces materials in bulk form, enabling evaluation of its properties in a standard cell configuration. This allows simultaneous optimization of all aspects of the cell, including the active materials, binders, separator, electrolyte and additives. Wildcat is using this high throughput system to develop new electrode and electrolyte materials for a variety of battery types (primary, secondary, aqueous, non-aqueous). In this talk, I will discuss our latest discovery, a copper fluoride-based conversion electrode with excellent rate capability (95% capacity at 1C, 20 µm electrode), energy density (3,000 Wh/L), voltage hysteresis (0.3 V), and stable cycling.

2:30 柔軟性の高いリチウムイオン電池生産用レーザー印刷LiFePO4陰極におけるレーザー誘起3次元構造
Wilhelm Pfleging, PhD, Head of Laser Material Processing, and Johannes Proell, Institute for Applied Materials (IAM-AWP), Karlsruhe Institute of Technology (KIT), Germany
Since LiFePO4 is a promising cathode material due to its high safety issues and specific capacity, it suffers from poor Li-ion diffusion. In order to overcome these drawbacks, LiFePO4 has been laser-printed onto aluminum foil. This process enables highly porous structure and intrinsic active surface area. Further improvement of the cycling behavior is achieved by 3D surface structures formed by a laser structuring process. The combination of both techniques allows for novel cathode architectures with flexible design and improved lifetime.

The sources of raw materials and the synthesis procedure were carefully controlled for the mass production of LiFePO4 with good reproducibility. In this work, the effects of purity and stoichiometric compositions of iron raw materials on the electrochemical performance are presented. We will show our latest work in the consistency of performance of 1.5 tons of LiFePO4 cathode materials by measuring the capability process of key characteristics (Cpk).

3:30 リチウム電池の輸送に関する要件
Rich Bysczek, Global Technical Lead for Electric Vehicle and Energy Storage, Intertek
New United Nations (UN) regulations regarding the transportation of lithium batteries recently went into effect and were adopted by other global regulatory bodies.

Tsuyoshi Honma, PhD, Assistant Professor, Functional Glass Engineering Laboratory, Nagaoka University of Technology, Japan
Triclinic Na2−xFe1+x/2P2O7/C composite was prepared by glass-ceramics method. We found that Na2−xFe1+x/2P2O7/C composite can be used as cathode active materials for Sodium ion battery with high current density rate performance over 10C (2 mA cm−2) condition and stable electrochemical cycle performance. A 2 μm glass precursor powder in composition of Na2−xFe1+x/2P2O7 (x = 0-0.44) was crystallized in tubular furnace around 600 °C with carbon source to reduce iron valence state and to coat grain surface with carbon. By means of charge-discharge testing Na2FeP2O7/C composite exhibits 86 mAh g−1 (253 Wh kg−1) as reversible discharge energy density that is half amount of that for LiFePO4, however in 10C condition they kept 45 mAh g−1 (110 Wh kg−1) even in 2 μm grain size.

LBNL has been working on a high-power redox flow battery (RFB) by utilizing hydrogen and bromine to develop a cost-effective electrochemical system for storing grid-scale energy. In this study, we will report on technical approaches, which have been taken to develop the RFB. It will be described in detail how cell components and structure could be optimized to minimize the losses associated with kinetics, ohmic and mass transfer properties, and therefore leading to the first-in-class RFB performance. We will also report on the cyclic performance of the RFB, and especially the effect of operating conditions such as electrolyte concentration, cut-off potential, and current on the cyclic performance. Various diagnostic methods such as measurement of over-potential with open-circuit-voltage (OCV) monitoring cell, analysis of exit gas from cell with a real time gas analyzer (RTGA), and characterization of species cross-over by capillary electrophoresis (or bromide-selective electrode) were utilized to find the proper operating conditions to minimize performance loss and side reactions. This work was funded by Advanced Research Projects Agency-Energy (contract # DE-AC02-05CH11231) with cost share provided by Robert Bosch LLC.

11:30 大型リチウムイオン電池システムの安全性
Bart Mantels, Project Coordinator, VITO unit Energy Technology, Belgium
Until now, no systematic and comprehensive assessment of Li-Ion system safety exists for large grid-connected electric energy storage systems. This project developed and validated a framework for assessing the safety and reliability of large battery systems throughout the entire life cycle and at all levels of the system, building upon the generally accepted failure mode, effect analysis (FMEA) approach. This is a bottom-up analytical safety assessment that searches for potential failure modes, which is widely used in product development.

Carlos Ziebert, PhD, Researcher, Institute for Applied Materials & Applied Materials Physics, Karlsruhe Institute of Technology, Germany*
Commercial 40Ah NMC Li-Ion pouch cells were cycled under isoperibolic and adiabatic conditions at rates up to 1C in an accelerating rate calorimeter to investigate performance and thermal behavior. Heat capacities, and total generated heat were measured after calibration using Al alloy dummy cells and the latter was separated into reversible and irreversible parts by potentiometric and current interruption technique. All these data are needed for thermal modeling and management.

3:00 ドイツ連邦教育研究省(BMBF)のSafeBattプロジェクトと18650型市販リチウムイオンセルに対する釘刺し試験の導入
Jan Haetge, PhD, Research Scientist, MEET - Battery Research Centre, University of Muenster, Germany
The presentation introduces the new beacon project SafeBatt that is funded by the German Federal Ministry of Education and Research (BMBF). The consortium consists of automotive manufacturers, supplying companies and academic institutions that cooperate to enhance the reliability and safety of lithium-ion batteries. The project focuses on improving the cell chemistry to increase the intrinsic safety of the battery and the implementation of sensors to monitor the safety relevant parameters inside the cell. Another topic is the optimization and standardizing of safety test procedures to validate safety concerns for state-of-the-art batteries and batteries with improved cell chemistry. MEET contributes with aging and safety tests of full cells and develops electrolytes with enhanced safety. Nail penetration tests in adiabatic conditions were performed in an accelerating rate calorimeter (ARC) to generate internal short circuits in commercial 18650 lithium-ion cells. We tested a selection of different cell chemistries with different states of charges (SoC). Through performing the measurements in adiabatic conditions, a detailed description of the temperature and pressure progress during the battery abuse is feasible. For future studies the ARC will be extended with further analytic instruments to perform online analytic measurements of the evolving gaseous products.

Deng-Tswen Shieh, PhD, Researcher, Dept of Lithium Battery Reliability Design, Material & Chemical Research Laboratories, Industrial Technology Research Institute, Taiwan R.O.C.
For nail penetration test the signal of voltage and temperature are important safe index. Up to now temperature detection is only capable of measuring surface of the battery, what happened on the point of short is keen to be understood. The special design with thermocouple embedded inside the tip of nail can help us detect real temperature reliably and do quantitative analysis. With such method and device, we test lithium-ion battery cell by introducing different nail shape and material under different test conditions. This test method has the capability to quantify the safety of battery to several levels and therefore guide the material system design quantitatively, which can be a good screening method to differentiate the safety level of battery and material system design.

9:00 ソフトウェア短絡検査がリチウムイオンセルの内部欠陥を示す優れた指標になる可能性
Judith Jeevarajan, PhD, Battery Group Lead for Safety and Advanced Technology, NASA Johnson Space Center
Several methods exist that can predict whether a li-ion cell has an internal defect. Some of those are self-discharge tests at end of charge voltages, soft short tests at the end of discharge voltages, etc. It is also not clear if these tests are a good reflection of contaminants or other types of defects inside the cell. This paper will address the topic of whether there is a good method to detect internal cell defects in li-ion cells.

9:30 内部短絡発生装置の開発(米エネルギー省再生可能エネルギー研究所(NREL)/米航空宇宙局(NASA))
Matthew Keyser, Senior Engineer, Vehicles and Fuels Research, National Renewable Energy Laboratory
NREL has developed a device to test one of the most challenging failure mechanisms of lithium-ion (Li-ion) batteries—a battery internal short circuit. Many members of the technical community believe that this type of failure is caused by a latent flaw that results in a short circuit between electrodes during use. As electric car manufacturers turn to Li-ion batteries for energy storage, solving these safety issues becomes significantly more urgent. Due to the dormant nature of this flaw, battery manufacturers have found it difficult to precisely identify and study. NREL's device introduces a latent flaw into a battery that may be activated to produce an internal short circuit. NREL uses the internal short circuit device to better understand the failure modes of Li-ion cells and to validate NREL's abuse models. The device can be placed anywhere within the battery and can be used with both spirally wound and flat-plate cells containing any of the common Li-ion electrochemical systems. Producing a true internal short, the device is small compared to other shorting tools being developed by industry and does not rely on mechanically deforming the battery to activate the short, as do most of the other test methodologies. With the internal short in place, the battery can be used and cycled within normal operating conditions without activating the internal short device. This allows the battery to be aged prior to activation. The internal short produced by NREL's device is consistent and is being developed as an analysis tool for battery manufacturers and other national laboratories as well as OEMs. This has broad-reaching applications as automakers bring electrified vehicles to market in larger numbers. NREL's presentation will outline the differences in the voltage and temperature response between the four different types of internal shorts within a battery. We will also present results showing the difference between a foil to foil internal short when a shutdown and non-shutdown separator are used in an 18650 LiCoO2 cell.

10:00 高出力用途に対応するリチウムイオン電池の安全検査
JaeSik Chung, PhD, CTO, PCTest Engineering Laboratory
The adoption rate of LiB in high power applications has getting increased but the test information for its cell abuse and safety test was not reported much yet compare to that of small portable electronics. Besides, the operating conditions and usage environment of the high power application, especially power tool application, are much harsher than that of small portable electronics so that the test items and conditions for the high power application should be considered more carefully to simulate adequately the cell abuse conditions in connection with the devices. In this presentation, we will report the cell abuse safety testing (simulation in electrical, mechanical and thermal and thermal behaviors) for the high power application cells and compare the results between cell capacities and will discuss about those implications.

Safe, high performance cells are required to power next generation technologies. However, increasing energy densities of batteries tighten the required tolerances and the potential for catastrophic system failure. Physical Sciences Inc. has developed in-situ coatings that maintain the required high performance levels, while improving the abuse tolerance of cells. This presentation will discuss the results of these development efforts and highlight the performance benefits these technologies offer.

12:00 組み込み型ファイバーブラッググレーティングセンサーによるリチウムイオン電池セル内の熱発生に関する実験研究
Gwo-Shyang Hwang, PhD, Scientist, Department of Mechanical Engineering, National Taiwan University, Taiwan R.O.C.*
The performance and safety of Li-ion batteries have close relationships with the thermal environment inside and outside battery cells. It is well-known that poor thermal management will result in fast degradation of Li-ion batteries and even a hazardous condition such as thermal run-away. Hence, a vast amount of research has been devoted to studying the thermal behavior of Li-ion cells and its relation with the electrochemical and chemical processes during charge and discharge. However, due to the lack of direct measurements of temperature inside the Li-ion cells, it was normally resorted to numerical simulations based on thermal-electrochemical models in the past research. Although the simulation results appear to have good agreements with experimental data excluding interior temperature of battery cells, it is difficult to verify the accuracy of the simulated thermal behavior inside battery cells. In this research, the Fiber Bragg Grating (FBG) sensor is adopted as an embedded temperature sensor for a Li-ion battery cell by exploiting its merits: it is chemically inert; it can withstand high temperature (up to 250 °C for non-decay reflection spectra), and it can be connected in series (multiplexing). Besides the average temperatures, temperature gradients along a fiber grating can be derived from its measurements in real-time. Based on the measured average temperatures and temperature gradients inside a Li-ion cell, insights of the thermal behavior of a Li-ion battery can be obtained.

George M. Lloyd, PhD, Staff Scientist, ACTA Inc., and
P. P. Mukherjee, PhD, Prof, Energy and Transport Sciences Laboratory, Texas A&M University

We overview the methodology underlying a proportional hazards model (PHM) that establishes a framework ideally suited for performing reliability estimates for lithiubased batteries. We establish the notion of covariate trajectories, which can include both intrinsic battery factors (morphology, etc.) and extrinsic factors (environmental histories, in particular). The methodology allows prediction of battery reliability among a discrete set of non-stationary stochastic environments or along an arbitrary stochastic covariate trajectory. Such scenarios are typical for batteries, which are typically used for portable and mobile applications such as electric vehicles. The framework yields the expected value of prognostic statements, sample realizations, and a non-parametric estimate of the corresponding distributions in order to infer extreme event probabilities. Implementation of the model itself is well within the capabilities of current embedded processing architectures commonly found on battery-powered systems.
 
2:30 予測シミュレーションによる電池の安全性向上
John A. Turner, PhD, Group Leader, Computational Engineering & Energy Sciences Group, Oak Ridge National Laboratory
Modern battery packs store a significant amount of electrochemical energy that can pose a safety risk uncontrollably released. A comprehensive computational model for the battery configurations would enable us to expand the parameter space of adverse conditions and accident scenarios beyond what can be tested experimentally. We describe the development of computational models for simulating mechanical, electrochemical, and thermal responses of the prismatic and cylindrical battery cells under both normal and abnormal conditions. The models are based on finite element method (FEM) formulations of the partial differential equations describing the above physical phenomena. Algorithmic, implementation and computational details are described, and model calibration and comparison of the simulations with the ongoing battery safety experiments will be presented.

4:00 ファラデーの電磁誘導の法則に基づく最新の金属汚染物検出システム
Saburo Tanaka, PhD, Prof, National University Corporation, Toyohashi University of Technology, Japan
For manufacturers producing Li-ion batteries or its materials, problems with metallic contaminants are critical issues. When contamination occurs, the manufacturer of the product suffers a great loss from recalling the tainted product. The lower detection limit for practical X-ray imaging is on the order of 1 mm. A detection system using a SQUID is a powerful tool for sensitive inspections. We previously proposed a direct detection system using multi-channel SQUIDs. In that system, an object with a contaminant is magnetized by a permanent magnet, and then a SQUID detects the remnant field of the contaminant. Because the detection width is defined by the size of the SQUID, eight-channel SQUIDs are required to inspect a specimen with a width of 65 mm, for example. This procedure is costly, and as a result, the system has not been widely used in the field. To circumvent this problem, we propose an indirect high-Tc SQUID magnetic metallic contaminant detector combined with a coil and magnet. The principle of the system is based on Faraday's law of electromagnetic induction. The detection section consists of permanent magnets and copper-wound pickup coils. The signal is magnetically transferred to a SQUID magnetometer. The differential pickup coil successfully measures an iron test piece with a size of 40 µm when the test piece was moved with a speed of 100 m/min. The advantage of this indirect detection method is that the detection width is wider than the previous SQUID direct detection method. The detector is able to detect a 50-µm iron test piece within a range of 20 mm with an SNR greater than 5. Since two coils are differentially connected in series, a detection width of 40 mm (2 - 20 mm) per channel is realized and two SQUIDs are sufficient for an inspection width of 65 mm. This is a great advantage compared to the direct detection system, which requires eight-channel SQUIDs to inspect an object with a width of 65 mm. This detection method is effective for the inspection of non-metallic materials such as the plastic film separator of a Li-ion battery. If the criterion of the detection size is moderated and 100 um, the SQUID sensor can be replaced by a low cost flux gate magnetic sensor. In the case, the cost of the system is dramatically reduced. In my talk, the evaluation results of the indirect contaminant detection system using a flux gate magnetic sensor will be also discussed.
