LiPO2F2 as a LiPF6 Stablizer Additive to Improve the high- temperature Performance of the NCM811/SiOx@C Battery
2019
International Journal of Electrochemical Science
Fluoroethylene Carbonate (FEC) is an indispensable additive to improve the cycle stability of silicon cathode, but the incompatibility between FEC and LiPF6 seriously damages the high temperature performance of NCM811/SiOx@C. In this paper, the LiPO2F2, tris(trimethylsilyl) borate (TMSB) and tris(trimethylsilyl) phosphate (TMSP) were added as stabilizer to increase the compatibility between LiPF6 and FEC at elevated temperatures. The visual experiments show that the traditional LiPF6 stablizer
