Explosivity of lithium perchlorate in gel polymer electrolytes

In this article, we report the synthesis and characterization of novel methacrylate‐based polymer electrolyte membranes for lithium batteries. The safety requirement is a top priority for rechargeable Li‐ion batteries, and especially these are used in hybrid electric vehicles and power tools. After several serious fire accidents, the safety must be submitted to the intensive investigation and this danger must be minimalized. This article describes the differences between lithium perchlorate and tetrafluoroborate as conductive component in methacrylate‐based gel electrolytes. The gel polymer electrolytes were prepared by UV irradiation process, which is well known for being easy, low cost, and fast. POLYM. COMPOS., 34:1969–1973, 2013. © 2013 Society of Plastics Engineers
