【 摘 要 】

Lithium bis(oxalato)borate (LiBOB) is a promising salt for Li-ion batteries owing to its excellent characteristics, and its most outstanding performance is SEI film-forming ability. Here, we use the film-forming properties of LiBOB, cells with LiBOB electrolyte system first run 3-5 cycles in battery tester, making the formation of a robust SEI film on the MCMB surface, then use the pre-filming MCMB electrode and LiPF6 electrolyte to assemble new cells and to conduct electrochemical test. The pre-film was found to effectively retard the re-decomposition of the solvent.
