Progress in studies of organic electrolyte materials for Li-ion batteries

Recent studies on the organic electrolyte materials for Li-ion batteries were reviewed.The materials include lithium electrolyte salts,organic solvents and additives.These new lithium electrolyte salts include:(1)LiTFSI and its analogous salts;(2)lithium chelatoborates;and (3)lithium chelatophosphates.The research on organic solvents focus on the new-style organic solvents.The most important additives include:(1)the additive that is maily used to improve the performance of SEI film on carbon cathode;(2)the addivtive for overcharge protection;and(3)ion and anion receptor additives.
