Detection toward early-stage thermal runaway gases of Li-ion battery by semiconductor sensor

Abstract While achieving remarkable commercial success, lithium-ion battery (LIBs) carry substantial safety risks associated with potential thermal runaway during widespread applications. When operated under complex working conditions, particularly in high-temperature and high-pressure environments, the internal galvanic reactions within these batteries may escalate uncontrollably. During the early stages of LIBs thermal runaway, substantial amounts of characteristic gases such as H2, CO, and...
