電池安全性・セルエンジニアリング・電池管理システムの改良を通じた、より良い電池の構築
2023年12月12日〜13日
電池技術が改善され続けるにつれ、セルの活物質の利点を最大限引き出せる、技術的に優れた電池システムの需要も拡大しています。信頼できるセル性能を保証する電池パックを開発し、それを車両に組み込むことで、制約条件を満たしつつ安全性・信頼性・耐久性を確保できるようにする必要があります。セルの設計(非活性材料の選択を含む)は、電池の性能や信頼性に多大な影響を及ぼします。電池パックの設計・統合には、セル用化学物質の時とは全く異なる、熱工学・機械工学・電気工学上の課題が含まれています。各々の用途の負荷サイクルに応じてセル・パックの設計を最適化するには、セルやパックのエネルギー・電力・製造可能性・乱用耐性・熱特性・コストなどの間のバランスを注意深く保つ必要があります。

BATTERY MANAGEMENT FOR LITHIUM-METAL
リチウム金属電池の管理
Closed-Form Equations to Compute Impedance for Rechargeable Lithium-Metal Batteries with Application to Advanced Battery Management
Gregory L. Plett, PhD, Professor, Electrical & Computer Engineering, University of Colorado, Colorado Springs
Rechargeable lithium-metal batteries (LMBs) are viewed as the next important leap forward in lithium battery technology. Providing higher energy density than state-of-the-art lithium-ion batteries, LMBs have been largely held back by safety concerns and insufficient cycle life. Recent advances have made lithium metal viable for commercial production, though mathematical models of this chemistry have been slow to appear. This work introduces a closed-form impedance model for lithium metal chemistry and points the way toward reduced complexity model forms amenable to battery management system (BMS) applications.
A Control-Oriented Reduced-Complexity Model for Lithium-Metal Batteries with Application to Advanced Battery Management
Scott Trimboli, PhD, Associate Professor, Electrical & Computer Engineering, University of Colorado, Colorado Springs
Lithium-metal batteries (LMB) have recently emerged as a contender due to their inherently high specific energy (300 -550 Wh kg-1 versus 100-265 Wh kg-1 for lithium-ion), making them particularly appealing in heavy-duty class 4-8 trucks and buses. Advances in design have overcome many of the detractors (poor cycle-life and safety concerns) and LMB now show promise for commercial development. Like lithium-ion batteries (LIB), LMB require careful management to ensure good performance and safe operation. In this presentation, we will formulate a reduced-complexity single particle model (SPM) of LMB amenable to real-time battery management and advanced control.

Fire Suppression Studies for Lithium-ion Battery Fires
Judith Jeevarajan, PhD, Vice President and Executive Director, Electrochemical Safety Research Institute, UL Research Institutes
In the past few years, the Electrochemical Safety Research Institute (ESRI) team has been working on characterizing the efficacy of fire suppressants on various sizes and chemistries of lithium-ion modules. The fire suppressants that have been used repeatedly for the studies are nitrogen gas, water and a commercial aerosol-based fire suppressant. The time, duration and direction of release of the suppressants, as well as reignition after suppressant use, have been studied.
Benchmarking and Predicting the Risks of Li-ion Cells Undergoing Thermal Runaway.
Donal P. Finegan, PhD, Staff Scientist Batteries, Electrified Transport, National Renewable Energy Laboratory
With new designs and chemistries, the performance of Li-ion batteries increases year after year. The risks associated with thermal runaway of cells change too and a challenge persists in determining whether increased performance comes at the expense of reduced safety. This work focuses on understanding correlations between heat generation and mass ejection during thermal runaway, the causes of outlier behaviors, and the predictability of risks using zero- or one-shot learning.
New Requirements and New Solutions for Multi-Functional Venting Units
Michael Harenbrock, PhD, Principal Expert, Engineering Electric Mobility, MANN+HUMMEL GmbH
Multi-functional venting units are essential components in holistic battery safety concepts, enabling pressure equalization between pack interior and environment in regular operation, as well as effective overpressure release during thermal runaway, even reducing the risk of battery fires. With an increasing variety in battery pack designs and cell chemistries, the functionality of venting units must be adapted accordingly. This presentation will show current trends and solutions in venting unit engineering.

Cell Structure Engineering for Extreme Fast-Charging of LFP-Based Lithium-ion Batteries
Ryan Longchamps, PhD, Head Product Development, Engineering, EC Power LLC
Lithium iron phosphate (LFP)-based lithium-ion batteries enable moderate range electric vehicles with safe batteries that approach mass-market acceptable price points. However, the challenge of reaching "refill" times comparable to user expectations (e.g., <10 min.) persists. This talk presents EC Power’s thermally modulated cell structure, which permits extreme fast charging of ~170 Wh/kg LFP-based lithium-ion cells with long cycle life at both room temperature and -50 degrees Celsius.
Extreme Fast-Charging
Eric J. Dufek, PhD, Research Scientist & Group Lead, Energy Storage & Advanced Vehicles, Idaho National Laboratory
Fast-charging can readily lead to early cell failure and reduced performance. The ability to use cell parameters for the development of advanced charge protocols provides an opportunity to tailor both the time and energy accepted to specific needs while minimizing degradation. During this talk, advanced protocols and analysis, including the use of machine learning to identify failure modes and predict performance, will be discussed.

Challenges with Scaling-Up PPR Battery Designs from 18650 to 21700 Cells
Eric Darcy, PhD, Battery Technical Discipline Lead, Power Systems, NASA Johnson Space Center
NASA has 3 design approaches for achieving passively propagation-resistant battery designs with 18650 cells. The interstitial heat sink approach is most volumetrically efficient and achieves 459 Wh/L using 18650 cells 725 Wh/L. Scaling-up this design to 21700 designs that are >725 Wh/L presents challenges to demonstrate similar adjacent cell protection from conducted heat through the heat sink and from ejected heat diverted by blast plate barriers and channels.
Scaling-Up Laser-Ablation for Roll-to-Roll Structuring of Fast-Charging and Long-Life Electrodes
Donal P. Finegan, PhD, Staff Scientist Batteries, Electrified Transport, National Renewable Energy Laboratory
Controlling the microstructure of porous Li-ion electrodes can considerably improve their energy- and power-density. However, scale-up of cost-effective structuring techniques to high-throughput roll-to-roll production is challenging. In this work, we focus on the use of laser-ablation for high-throughput roll-to-roll production of structured electrodes, with enhanced fast-charging and long-life capability. This talk will cover the challenges, performance benefits, and economics associated with scaling to roll-to-roll production of laser-ablated structured electrodes.
Direct Comparisons of Pilot-Scale Li-ion Cells in the Formats PHEV1, Pouch, 18650, and 21700
Thomas Waldmann, Project Manager & Scientist, ECM, Zentrum fur Sonnenenergie und Wasserstoff Forschung ZSW
We compare the cell formats PHEV1, pouch, 21700, and 18650 with the same cell chemistry on pilot-scale. Conclusions are drawn on the effect of cell design on rate capability, cell resistance, heating behavior, and cycling aging. The results are put into context with commercial cells.

A Sustainability Perspective on Near-Future Energy Storage Technologies
Ulderico Ulissi, PhD, Manager, 21C Lab, Contemporary Amperex Technology Limited (CATL)
Energy storage technologies are critical to limiting emissions, and lithium-ion batteries (LIBs) are a key technology for many applications, including automotive and stationary storage. Therefore, we expect the LIB market to continue growing rapidly. This growth is keeping up the momentum for LIB technological development, which has been largely driven towards decreasing costs and improving performance. However, as LIBs become ubiquitous it is also critical to correctly assess the sustainability impact of the technology. In this presentation, we will discuss the concept of sustainability, how it is linked to Environmental, Social, and Corporate Governance (ESG) criteria, and will critically review the realistic opportunities to make batteries more sustainable in the near future. This will provide the audience more insights into the CATL carbon neutrality plan, and into its pledge to achieve carbon neutrality in its core operations by 2025 and across the battery value chain by 2035.
