Abstract

A safe electrolyte based on an ionic liquid–organic composite with binary additives was prepared. The stable solid electrolyte interphase (SEI) forms on the surface of a carbon anode by addition of vinylene carbonate (VC) and lithium bis(oxalato) borate (LiBOB) binary additives in ionic liquid–organic electrolyte mixture. The stable SEI effectively prevents the co-intercalation of PP13+ cations, thus leading to an obvious improvement in the performance of the cell.
