Advancing Battery Safety: Unveiling Thermal Runaway with a Custom Test Bench

Thermal runaway poses a critical challenge in the safe operation of lithium-ion batteries. This study is focusing on TR (Thermal Runaway) experiments conducted within a unique spherical test bench, aiming to explore and compare the thermal behaviors of LFP (Lithium Iron Phosphate) and NMC (Nickel Manganese Cobalt Oxide) cells. The investigation seeks to scrutinize existing notions that LFP cells inherently manifest enhanced safety compared to NMC cells, while also shedding light on the diverse thermal behaviors exhibited by these two most common battery chemistries.
