摘要：Lithium bis(oxalato)borate (LiBOB) has attracted much attention as a lithium salt or an additive in non-aqueous electrolytes for lithium-ion battery. In this work, the formation of a solid electrolyte interphase (SEI) film of MCMB (mesophase carbon microbeads) with LiBOB- sulfolane (SL) / dimethyl sulfite (DMS) electrolyte is studied. The result shows that Li/MCMB cell with LiBOB-SL/DMS electrolyte at high temperature exhibits lower impedance than that at room temperature. The SEM images demonstrates that the LiBOB-SL/DMS electrolyte at high temperature shows more excellent film-forming characteristics. It suggests that LiBOB-SL/DMS electrolyte is a promising formation of the solid electrolyte interphase.
