Battery Safety


As lithium-ion batteries become increasingly more powerful and engineering strategies advance, battery regulations and safety testing must evolve to keep stride with R&D advancements. Regulatory associations, battery manufacturers, cell R&D engineers and reliability engineers must develop robust and reliable tests for the progressively complex cells. Maintaining pack stability and mitigating thermal runaway to improve safety are vital to bring cells in R&D to market. Join us and enter the discussion that is making batteries safer.

8:40 Progress in Battery Safety Performance Simulation

Ted_MillerTed J. Miller, Manager, Energy Storage and Materials Strategy and Research, Ford Motor Company

Advanced automotive batteries are the critical enabling technology for vehicle electrification. Ford has undertaken development of a battery safety simulation tool. This is a first-of-its-kind multi-physics (combined mechanical, electrical, electrochemical, and thermal) CAE tool to predict battery response to a range of abuse conditions including crush due to crash and/or battery regulatory tests, short circuit, overcharge, and thermal ramp. An update on development progress and results from the alpha version of the prototype tool will be presented.

9:10 U.S. Department of Energy Electric Vehicle Battery Research Pathways and Key Results

Brian Cunningham, Engineer, U.S. Department of Energy

The U.S. Department of Energy set key technical targets necessary to enable Electric Vehicles (EV) to be as affordable as gasoline vehicles by 2022. A focus of this effort is the development of more cost-effective, longer lasting, and more abuse-tolerant EV batteries. VTO’s battery R&D effort includes multiple activities, ranging from battery materials research to battery cell and pack development and testing. This paper will highlight the current battery R&D pathways supported by VTO and key technical results from 2016.

2:15 FEATURED PRESENTATION: Applications of Internal Short Circuit Detection and Examples of Early Implementations

Brian Barnett, Ph.D., Vice President, CAMX Power

Recent events have heightened awareness that internal short circuits are a major cause of Li-ion battery safety events. We have developed multiple, distinct, non-invasive and chemistry-agnostic technologies for sensitive early detection of internal shorts in Li-ion batteries before the shorts pose a thermal runaway threat. We are implementing short detection for several applications and will describe examples of its use and benefits.

2:45 Modeling Mechanical Failure of Lithium-Ion Batteries to Improve Battery Safety

Shriram Santhanagopalan, Ph.D., Engineer, Transportation and Hydrogen Systems Center, National Renewable Energy Laboratory

In order to better understand the behavior of lithium-ion batteries under mechanical abuse, a coupled modeling methodology encompassing the mechanical, electrical and thermal response is presented for predicting short-circuit under external crush. Predicted damage of the individual layers within the cell under an indentation test are compared against experimental results. The electrical-thermal simulation predicts the current density and temperature distribution in a reasonable manner.

4:30 Monitoring the Strain Evolution of Lithium-Ion Battery Electrodes Using an Optical Fiber Bragg Grating Sensor

Chang-Jun_BaeChang-Jun Bae, Senior Researcher, Korea Institute of Material Science (KIMS), formally working at Palo Alto Research Center (PARC)

More advanced characterization and developmental tools are essential to improve performance and safety of Li-ion batteries. As a practical solution for in situ monitoring of realistic battery cells, we have implanted fiber optic sensors within the individual electrodes to monitor the internal electrode strain during cycling, demonstrating the feasibility and utility of FBG sensors to be used as diagnostic tools.

5:00 Using Instrumented Li-Ion Batteries to Understand Battery Performance

Rohit Bhagat, Associate Professor, University of Warwick

We present our work related to embedding sensors within commercially available cylindrical format cells. The types of sensors include reference electrodes for measuring half-cell voltages during operation and optical fibres to measure thermally induced strain. Embedding these sensors is not trivial as the performance of the cell must be unaffected by the modifications. The embedded sensors must survive the cells’ internal environment. These instrumented cells are a powerful tool to investigate battery performance such as fast charging and aging.

5:30 Transition to Breakout Discussions

5:35 Interactive Breakout Discussion Groups

Participants choose a specific breakout discussion group to join. Each group has a moderator to ensure focused discussions around key issues within the topic. This format allows participants to meet potential collaborators, share examples from their work, vet ideas with peers, and be part of a group problem-solving endeavor. The discussions provide an informal exchange of ideas and are not meant to be a corporate or specific product discussion.

8:25 Redox Shuttle Additives towards Safer Lithium-Ion Batteries

Lu Zhang, Scientist, Energy Storage Research, Argonne National Laboratory

In this talk, a molecular engineer approach of redox shuttle molecules will be discussed, which will introduce the stepwise evolution of ANL family of redox shuttle additives that have been developed at Argonne National Laboratory. Quite a few additives will be discussed in detail to exemplify the development progress. For instance, ANL-8 was developed by asymmetrical incorporation of ether chain to the dimethoxybenzene base. Due to its asymmetric structure and strong polarity, ANL-8 is liquid at room temperature, which dramatically improves its solubility and overall compatibility. ANL-8 delivers excellent overcharge protection to LFP lithium-ion cells.

8:55 Mechanical Abuse Tolerant Li-Ion Batteries

Michael_NaguibMichael Naguib, Research Staff, Materials Science and Technology, Oak Ridge National Laboratory

Herein a new electrode design, guided by modeling, that is intended to reduce the likelihood of thermal damage in the event of mechanical abuse will be discussed. A proof-of-concept showed that upon impact or deformation, such as in a vehicle accident, batteries’ electrodes break into electrically isolated segments limiting the current, therefore thermal-runaway can be avoided.

10:40 How the Electric Vehicles Catch Fire After Wading or Soaked in Water

Henry Mao, Ph.D., Youllion Battery Ltd., China

This talk relates a potential public hazardous situation for EV’s and PHEV’s. Approximately 16 of the $100,000+ Fisker Karma extended-range luxury hybrids caught fire and burned to the ground after Hurricane Sandy’s storm surge breached the port submerged the cars in Port Newark on Nov 21, 2012. Many more pure electric buses and cars caught fire in deep water in many Chinese city streets after heavy rain with failed sewage systems in the summer of 2016. No scientific answers from battery community on why the EV cars caught fire after soaked in water was published up to now. This talk will show solid evidence to explain why it happens and suggest a few preventative measures.

1:25 Surprising Chemistry in Li-Ion Cells

Jeff DahnJeff Dahn, Ph.D., FRSC, Professor of Physics and Atmospheric Science, NSERC/Tesla Canada Industrial Research Chair, and Canada Research Chair, Dalhousie University

It is important to increase the operating voltage of NMC Li-ion cells to obtain higher energy density. However, the electrolyte reacts with the positive electrode at high voltage. Using simple experiments involving only pouch bags, we show that the products of these reactions are extremely harmful to the positive electrode. This talk demonstrates how these harmful reactions at the positive electrode can be virtually stopped, leading to superb NMC Li-ion cells that can operate at high potential.
