Experimental Techniques to Determine Safety of Lithium-ion Batteries

Lithium-ion batteries (LIBs) have raised increased interest due to high energy density and efficient energy storage. However, safety is a major concern, and a large number of LIBs have been recalled due to explosion and fire accident. The safety of batteries is determined by the battery chemistry, its operating environment and its abuse tolerance. The webinar will cover various techniques to determine the safety parameters of cell and battery materials under thermal abuse conditions. For example, Onset temperature of self-heating, heat of reaction, separator shutdown temperature, leak/vent temperature, ignition temperature, vent pressure, and amount of gas generation.

This webinar is a recording from last year. You can still ask questions at any time during the webinar - we will answer them via e-mail afterwards.

Presenter: Surendra K. Singh, Ph.D., Belmont Scientific, Inc. 
Dr. Singh is the founder and president of Belmont Scientific, Inc. (BSI). BSI is a contract research and testing laboratory and provides services in the area of chemical process safety including safety evaluation of batteries and pressure relief systems design and evaluation. Dr. Singh’s experience in thermal sciences includes evaluation of the stability of chemicals and their fire and explosion hazard potential using various instrumental techniques, including calorimetric, minimum ignition energy (MIE) apparatus, 20-liter sphere for dust and gas explosion (KSt value), BAM oven for flammability and blasting cap testing for shock sensitivity.
