Research on stimulation responsive electrolytes from the perspective of thermal runaway in lithium-ion batteries: A review

At present, there are few reviews on the comprehensive discussion of thermal runaway and stimulation responsive electrolytes in lithium-ion batteries (LIBs). The harmful consequences caused by thermal runaway of LIBs are serious and worthy of attention. Therefore, in this manuscript, we first review the causes of thermal runaway in LIBs and the safety accidents caused. Then effective measures to prevent thermal runaway were discussed, among which starting from the battery itself is an effective way to control thermal runaway. As the electrolyte is the core of the four major materials of lithium-ion battery, the development of stimulation responsive electrolyte and its application prospect are discussed in the end, aiming at promoting safer stimulation responsive electrolyte design for lithium-ion battery.
