In-situ explosion limit analysis and hazards research of vent gas
In this work, an innovative combination of gas composition analysis and in-situ detection was used to determine the BVG (battery vent gas) explosion limit of NCM 811 (LiNi 0.8 Co 0.1 Mn 0.1 O 2) lithium-ion batteries, which revealed that as the battery SOC (state of charge) increases, LEL (lower explosion limit) first increases and then decreases, UEL (upper
