Influence of thermal initiators on the electrochemical performances of gel polymer electrolytes

采用热重/差热分析方法研究了两种热聚合引发剂:AIBN和BPO.它们通常用于制备锂离子二次电池凝胶态聚合物电解质.采用不同引发剂制备的凝胶态聚合物电解质具有不同的特性并影响聚合物锂离子二次电池的性能,例如倍率性能,高低温性能和循环性能.为凝胶态聚合物电解质体系选择了一种合适的热引发剂.Two thermal polymerization initiators, 2, 2'-azobisisobutyronitrile (AIBN) and benzoyl peroxide(BPO), commonly used to prepare gel polymer electrolytes (GPEs) for lithium-ion polymer batteries (LiPBs), were studied by thermogravimetry/differential thermal analysis (TG/DTA). The GPEs prepared with thermal initiators showed different electrochemical performances and had great influence on the performance of LiPBs, such as rate capability, temperature reliability, and cycling performance. An appropriate thermal initiator is selected for the GPE system.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000239177800011&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701SCI(E)中文核心期刊要目总览(PKU)中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)107826-8302
