9:00 電気自動車のための変換エネルギー貯蔵技術:ARPA-Eポートフォリオの概要
Ping Liu, PhD, Program Director, ARPA-E, U.S. Department of Energy
Advanced Research Projects Agency Energy (ARPA-E) has invested in transformational energy storage technology to enable more widespread adoption of electric vehicles (EVs). This presentation will highlight some of the promising projects that are helping to drive down cost, increase range, and improve safety for EVs. Approaches for improvement include novel materials for battery architectures, lithium-air, and flow batteries. There is also a group of projects with a focus on robust designs: electrochemical energy storage chemistries and/or architectures (i.e. physical designs) that avoid thermal runaway and are immune to catastrophic failure regardless of manufacturing quality or abuse conditions.

9:30 ナトリウムイオン電池用ピロリン酸鉄ナトリウム陰極ガラスセラミック
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.

10:00 ナトリウム伝導素材のための材料設計
Taku Onishi, PhD, Assistant Professor, School of Engineering, Department Chemistry for Materials, Mie University, Japan
A sodium ion conductor for a sodium ion secondary battery was theoretically designed by hybrid DFT calculations. It was concluded that NaAlO(CN)2 shows the high sodium ion conductivity along Z-axis. The activation energy along Z-axis was estimated to be 0.06 eV. Chemical bonding analysis on conductive sodium was also performed, based on Onishi chemical bonding rule.

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 PSIのシリコンウィスカとカーボンナノファイバー複合アノードを使った高エネルギー密度セル構築の取り組み
Christopher M. Lang, PhD, Group Leader, Energy Technologies, Physical Sciences Inc.
Silicon is one of the most appealing anode materials for higher energy density batteries. However, many challenges exist to efficiently access the large theoretical potential of this material. Physical Sciences Inc. has developed and demonstrated a composite material with good capacity, rate and cycling performance. In this presentation, we will present on our efforts to construct high energy density cylindrical and prismatic cells with this anode material. In particular, the impact on cycling performance of the cathode material and electrolyte choice will be examined.

12:00 高エネルギーソリッドステート擬似キャパシター
Daniel Sweeney, PhD, Principal Investigator, Space Charge LLC
A solid-state pseudocapacitor promising high energy and power density pseudocapacitors are hybrid energy storage devices having the attributes of both batteries and true capacitors. Conventional pseudocapacitors utilize liquid electrolytes of very low dielectric strength, which ultimately constrain energy density. Space Charge LLC has substituted thin films comprised of materials, which have high dielectric strength and high ionic mobility. This combination of virtues supports charge storage exceeding that of advanced batteries while permitting rapid charging and potentially tens of thousands of charge-discharge cycles.

12:30 Knowledge Foundationメンバーシッププログラムの後援による昼食会

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.

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器同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.

8:00 展示品/ポスター観賞およびコーヒー、軽食休憩

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 無線電力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.
