Research progress in gas generation characteristics during the thermal runaway of lithium-ion batteries
摘要
Abstract
Lithium-ion batteries,with their high energy density,long cycle life and notable environmental friendliness,are extensively applied in various innovative technologies and green energy solutions.Nevertheless,the safety issues arising from the thermal runaway of lithium-ion batteries represent a significant barrier to their widespread application.By exploring and analyzing the gas generation characteristics of battery thermal runaway,it can provide effective guidance for the corresponding risk assessment and early warning.This paper first elucidated the gas generation mechanism and gas detection methods during the thermal runaway process of lithium-ion batteries,followed by a review of the latest research progress of these gas generation characteristics in different abuse conditions(thermal abuse,electrical abuse and mechanical abuse).Specifically,the paper focused on the influence of different electrode materials,state of charge,energy density,battery shape and environmental conditions on key parameters of gas generation including time,total volume,composition,temperature,toxicity and flammability risk in battery thermal runaway.Finally,the future research directions of lithium-ion batteries in terms of gas generation characteristics during the thermal runaway,gas detection methods,battery structure design and safety pre-warning were prospected.关键词
