Abstract
Lithium-ion cells have the highest energy density of the rechargeable cell chemistries in the commercial market. However, associated with this high energy density is also a very high propensity for these batteries to go into a thermal runaway under off-nominal events and abusive conditions. Past studies have indicated that the consequence of an off-nominal condition depends on the state-of-charge (SOC) of the cells. The current study was undertaken to test the cells under various states of charge (depths of discharge) to understand the safety tolerance of the cells at the different capacity levels.
