Abstract

The incorporation of additives designed to sacrificially react on the surface of cathode materials of lithium ion batteries has been investigated. Addition of low concentrations of either organic (2,5-dihydrofuran (2,5-DHF) or γ-butyrolactone (GBL)) or inorganic additives (lithium bisoxalatoborate (LiBOB), lithium difluorooxalatoborate (LiBF2(C2O 4)), tetramethoxytitanium (TMTi), and tetraethoxysilane (TEOS)) to 1 M LiPF6 in 1:1:1 EC/DEC/DMC improves the capacity retention of Li/Li1.17Mn0.58Ni0.25O2 cells cycled to 4.9 V vs Li. ©The Electrochemical Society.
