Battery Safety
( 電池安全 )

2020年3月31日~4月1日


An increasing number of high-energy density batteries are entering the market. As a result, it is becoming increasingly more important for battery safety testing and regulations to advance in stride with new technologies to ensure safe battery function and consumer use. This year's Battery Safety conference program, part of the International Battery Seminar & Exhibit, will cover important battery regulations and safety testing necessary to stay up-to-date with large R&D advancements. Regulatory agencies and associations, cell R&D engineers, and reliability engineers will discuss how they are developing robust and reliable tests for the progressively complex cell and pack designs. Maintaining battery pack stability and mitigating thermal runaway to improve safety will also be covered.

While current testing is still beneficial towards obtaining useful information, it is not specific enough to generate data for technological improvements that can have a major impact on the safety of battery design. This work proposes extending these standards to obtain specific information that pertains to how pouch cell Li-ion batteries respond to penetrations using a drop hammer test with a nail.

M. Stanley Whittingham1:40 The Li Battery: From Its Origin to Enabling an Electric Economy

M. Stanley Whittingham, PhD, SUNY Distinguished Professor, Member, National Academy of Engineering, Director, NECCES EFRC at Binghamton, SUNY at Binghamton

50 years ago, a rechargeable battery achieving an energy density exceeding 100Wh/kg at room temperature was just a dream. Today, cells are exceeding 250Wh/kg. These cells have revolutionized electronic devices, have made EVs feasible, are dominating grid storage, and enabling renewable energy. Yet the components of these intercalation-based cells have not changed significantly since the 1990s, and the cells still do not exceed 25% of theoretical capacity. Some of the challenges that need to be addressed to doubling the energy density will be discussed.

SAFETY TESTING & TRAINING

3:25 Chairperson’s Remarks

3:30 Cell Level Considerations for Next Generation Battery Management

Shriram Santhanagopalan, PhD, Transportation and Hydrogen Systems Center, National Renewable Energy Laboratory

4:00 Progress on In-Situ Instrumentation for Cell Safety and Performance Mapping

Alexander J. Roberts, PhD, Associate Professor in Energy Storage, Institute of Future Transport and Cities, Coventry University

The inclusion of sensors inside a cell offers valuable insight into electrochemical and thermal behaviour not possible from external measurement, with potential for greater understanding and extending safe operation limits particularly under higher current application. This work will detail advances in implementation at both cylindrical and pouch format, with variations between in-situ and ex-situ measurements discussed in light of accepted cell operational limits.

4:30 Developing Effective Section II Training

Anderson_DavidDavid Anderson, Director, Transportation Logisitcs, Logistics and Maritime Operations

The key to section II training is for a company to develop proper work aids for use on the job. Once developed, the work aids must be updated as regulations and the battery mix which the company ships change.

DESIGNING SAFER BATTERIES

8:25 Chairperson’s Remarks

8:30 Designing BMS for Safe 28V Aircraft Battery

Trung Nguygen, PhD, Vice President, Technical Management, EIC Labs

Safety is the primary criterion in the EIC 28V Li-ion aircraft battery pack’s design and architecture. A lithium-ion system can be safe, provided certain precautions are met when charging and discharging. For safe operation, the BMS continually monitors voltage, currents, and temperatures within the pack and protects the battery against adverse safety conditions, such as overcharge, over-discharge, short circuit, and high temperature.

9:00 Lesson Learned from PPR Testing of 160 Wh/kg High Power/Voltage Battery

Darcy_EricEric Darcy, PhD, Battery Technical Discipline Lead, Propulsion and Power Division, NASA-Johnson Space Center

New combination of thin steel rings around the spin groove of 18650 cells and ceramic putty interstitial material shows great promise at mitigating the hazard of side wall breaches during thermal runaway, while yielding 1 kWh battery deck assembly that exceeds 160 Wh/kg and is capable of 3C continuous discharge. Thermal gradient between cells found to be reduced dramatically with each cell in axial contact with an oscillating heat pipe technology to enhance cycle life and obviate cell balancing. Topology trade and analyses between P-S and S-P indicates vulnerability of each to propagation of thermal runaway due to a cell internal short circuit and favors S-P. Lastly, certain thin, lightweight barriers to cell thermal runaway ejecta are shown to prevent perforation of thin aluminum sheet metal panels and new flexible gas permeable membrane vents coupled with baffles, copper mesh, and screens are shown to prevent flames from existing the battery enclosure during a single cell thermal runaway event.

SAFELY INCREASING BATTERY LIFE

10:45 Investigation into Active-Mode Modulation of Parallel-Cell Battery Currents for Increased Battery Life and Safety

Brett Huhman, PhD, Senior Research Engineer, Plasma Physics Division, U.S. Naval Research Laboratory

It has been established that batteries using hard-bused connections are inherently unstable at high discharge rates. This paper evaluates the feasibility of using MOSFETs in the active mode to modulate the current from each battery string in a 19S4P array using Simulink and active feedback mechanisms. Discussion will include model development, results, and a path forward for experimental validation.

11:15 New Innovations and Techniques for Fractional Thermal Runaway Calorimetry (FTRC)

11:45 Mitigating Lithium-Ion Battery Degradation through a Novel Fast-Charging Strategy: A Jointed Experimental and Simulation Effort

Liu_LinLin Liu, PhD, Associate Professor, Mechanical Engineering, The University of Kansas

The lithium-ion battery degrades over time, which compromises its electrochemical performance and mechanical integrity, and eventually battery safety. An enhanced fast-charging strategy can overcome these limitations. This work proposes a novel fast-charging strategy to charge lithium-ion batteries safely. This strategy contains a voltage-spectrum-based charging current profile, which is optimized through an optimization framework with physics-based battery models and a genetic algorithm.
