Cathode solid electrolyte interphase generation in lithium-ion batteries with electrolyte additives
Date of Original Version
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.
