より良いバッテリーの開発
2023年6月20-21日
バッテリーエンジニアリングには、活物質の利点を最大限引き出せるような電解質・セルの設計、セル性能を確実に引き出せるパックの設計、バッテリーセルの車両(や他の機械)との一体化、車両の制約条件を維持しながらの安全性・信頼性・耐久性の確保、といった重要な側面が含まれています。 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。バッテリーパックの設計・統合には、セルの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・耐摩耗性・熱特性などの間のバランスを注意深く保つ必要があります。

SAFETY & REGULATIONS
安全性と規制
Performance and Safety Requirements in the New Battery Regulation
Andreas Pfrang, Scientific Officer, Joint Research Center, European Commission
The new Battery Regulation will limit EU sales to sufficiently sustainable batteries. For this purpose, the regulation covers the entire battery life cycle, from the extraction of raw materials to industrial production to end-of-life disposal. The European Commission's Joint Research Centre supports the development of the related requirements or test procedures scientifically. In this presentation, requirements related to performance and safety will be presented and discussed from a technical perspective.
Bio-Based Barriers for the Prevention of Thermal Runaway Propagation in High-Energetic Lithium-ion Battery Packs
Bruno Bausch, PhD, Center for Solar Energy and Hydrogen Research, ZSW
Due to the constant increase in energy density of lithium-ion batteries, safety concerns in case of a thermal runaway event become more critical. Thermal runaway propagation (TP) can destroy an entire LIB pack, rapidly releasing energy. A solution for TP that minimally affects the pack remains one of the main unsolved safety-related issues in battery systems. This presentation proposes an eco-friendly barrier that prevents thermal propagation between 50Ah LIB cells.

Impact of Data Window on Prediction of Battery Aging and Swelling
Anna G. Stefanopoulou, PhD, William Clay Ford Professor of Technology, Professor Mechanical Engineering, Professor of Electrical and Computer Engineering, University of Michigan
This work extends a scalable, equivalent circuit model (ECM) with heat release from chemical decomposition to capture the electrical and thermal behavior of a cell during an external short. To capture the stranded energy and likelihood of thermal runaway, the model should accurately predict the final state-of-charge (SOC) and peak temperature. A key advantage of the proposed approach is that the ECM parameterization can be performed under normal operating conditions reducing the amount of hazardous testing required. This can then be used to explore a controlled discharge by adjusting the external short resistance to avoid venting conditions.
Efficient Cell Aging Characterization
Stefan Scheidel, Senior Development Engineer, Methodology, AVL List GmbH
State-of-the-art cell aging characterization typically takes around 1.5 years and requires at least 40 cells. The current approach is using Design-of-Experiments (DoE), applying one current profile per cell from Beginning-of-Life (BoL) until End-of-Life (EoL). The presented approach suggests pre-aging of cells and changing current profiles per cell with an advanced DoE approach to reduce the time needed by ~60% and the number of cells needed by ~30%, with the same result quality as the aging model.

Nima Lotfi, PhD, Director, New Product Development, Bitrode Corporation
Battery data analytics is the cornerstone of the development and cycle life of any battery energy storage system as it can facilitate important stages such as cell characterization, modeling, and battery management system design and implementation. In this presentation, we will introduce Bitrode Digital Cycler (BTDC), the next generation of battery cyclers and discuss how it is designed to streamline and expedite battery data analytics and the overall battery development process.

CELL DESIGN
セルの設計
Cell Design on Target - Maximum Performance at Optimal Cost in Minimal Time
Michael Schoenleber, Co-Founder & CTO, Batemo GmbH
In this talk, we will present a digital cell design approach, which does not start the cell design process from the scratch, but from the physical model of an existing cell, where all electrochemical and geometrical properties are correctly digitally represented. From that point of very low model uncertainty but at the same time realistic level of complexity, cell design parameters can be systematically changed and their sensitivity on different cell performance indicators like capacity, peak power, or fast-charging capability can be studied
A Battery Diagnosis and Prognosis System for eVTOL Aircraft Battery Pack
Anup Barai, Assistant Professor, Energy & Electrical Systems Group, University of Warwick
The automotive BMS is perceived to be the best-in-class. This is due to the high volume, which enables the exploitation of the latest technology and commercial advantages. Yet, the diagnostic and prognostic capabilities implemented are limited. For electric aircraft, the fundamental premise of safety, plus the need to monitor, identify and isolate or mitigate battery failure is different. However, the tightly regulated aircraft usage case opens a few novel approaches to realise a comprehensive diagnostic and prognostic system. At WMG, in collaboration with aerospace OEMs, we are developing a battery functional safety diagnostic and prognostic system.
Reimagining the Battery Form Factor
Tim Holme, PhD, CTO, QuantumScape Battery Corporation
Lithium metal batteries generally expand and contract during charge and discharge. This presentation would address why existing cell formats (i.e., cylindrical, pouch, or prismatic formats) are not well equipped to handle this expansion, the properties an optimal format should have to maximize performance, and why this innovation matters to the battery industry at large.
Refreshment Break in the Exhibit Hall with Poster Viewing15:05
Increasing Battery Systems Performance
Kevin Konecky, Battery and Energy Storage Systems Consultant, Total Battery Consulting
Battery systems are complex systems with the battery cell as the core technology of the system but then integrated with multiple subsystems, including mechanical, thermal, and battery management systems (BMS). This presentation will look into the different subsystems that contribute to the overall battery system performance and opportunities for improvement in next-generation battery systems. Battery system trends in the industry will be evaluated and discussed.
Overcharging - Fast Charging
Yatish Patel, PhD, Research Associate Mechanics of Materials, Mechanical Engineering, Imperial College, London
A novel parametrisation testing technique is presented. It's then parametrised using this testing technique and compared to a model parametrised using current common testing techniques. This comparison is conducted using a WLTP (worldwide harmonised light vehicle test procedure) drive cycle. As part of the validation, the experiments were conducted at different temperatures and repeated using two different temperature control methods: a climate chamber and a Peltier element temperature control method.

Thermal Management Optimization for Large-Format Lithium-ion Battery Using Cell Cooling Coefficient
Gregory J. Offer, PhD, Professor in Electrochemical Engineering, Imperial College London
The journey of discovery this group has made over the past ten years in understanding lithium-ion battery degradation, how to model it, and how to diagnose it. The journey began with pioneering work demonstrating how different thermal management approaches strongly affected the degradation rates of lithium-ion pouch cells. At around the same time, the group began working on understanding and modeling the physical mechanisms of degradation.
Performance Optimization for Battery Cell, Module, and Pack Testing
Gerald Sammer, PhD, Principal Business Development Manager, Integrated & Open Development Platform, AVL List GmbH
Battery testing has a significant impact on the time-to-market of batteries and electrical vehicles. Testing hundreds or thousands of batteries and cells simultaneously and efficiently in a multi-vendor lab is a huge challenge. Efficient processes and an open toolchain for automated scheduling, monitoring, energy management, and data analytics are the key aspects of a competitive battery lab. This presentation explains AVL's approach on how to optimize a battery lab operation with a comprehensive methodology supported by a dedicated software solution open for any test equipment vendor.
