锂离子电池用高热稳定性新型隔膜的研究新进展
New development of novel separators with high thermal stability for lithium-ion batteries
摘要
Abstract
Lithium-ion batteries have been widely utilized in the new energy market due to their high energy density,long cycling life,and low self-discharge rate.However,the commonly employed polyolefin separators in lithium-ion batteries will shrink and meltdown at high temperatures,which can lead to the occurrence of battery thermal runaway.The development of novel separators with high thermal stability is expected to improve the safety of the battery.The latest research progress of new separators with excellent thermal stability in the field of lithium-ion batteries is systematically reviewed,and their design ideas and structure-activity relationship are discussed.At the same time,the key characteristic parameters of the above separators,such as thickness,ionic conductivity,thermal shrinkage,etc.,are summarized and compared.Finally,the future development direction of lithium-ion battery separators is prospected.关键词
