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.
