Battery Safety
NEW DATES - July 28-29, 2020
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.

1:40 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.

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**
David
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.

9:00 Lesson Learned from PPR Testing of 160 Wh/kg High Power/Voltage Battery
Eric 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.
9:30 Increasing Success & Safety Applying Lean Methodologies to Battery Testing**
Beran Peter, CEO, Associated Environmental Systems
Concepts in Lean Methodologies lend naturally to safer, more efficient, battery testing. By creating a scenario for managing high-density testing in small batches, it increases safety and reduces cost per channel. Safety is increased by limiting
propagation in the case of an event. Cost is reduced by utilizing standardized products.
9:45 Enabling the Next Generation of Batteries Through Safety
Jenna King, CEO, Amionx
SafeCore is a transformative technology that acts like a fuse to prevent lithium-ion batteries from being the source of a fire or an explosion, which is typically due to three primary causes: Overcharge, internal short or external heat. SafeCore
is activated by current. voltage or temperature thresholds.

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)

Walker, PhD, Aerospace Technologist, NASA-Johnson Space Center
11:45 Mitigating Lithium-Ion Battery Degradation through a Novel Fast-Charging Strategy: A Jointed Experimental and Simulation Effort
Lin 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.
