Progress in studies of lithium salts for Li-ion battery in nonaqueous electrolytes

Progress in studies of new electrolyte salts in recent years is reviewed. The methods of synthesis, components, structures, chemical and electrochemical properties, and the relationship between the properties and the structures of lithium electrolyte salts are introduced. These new electrolyte salts include lithium chelato-borates, lithium chelato-phosphates, lithium fluoroalkylphosphates, lithium superacid salts, lithium methides, lithium perfluoroalkylsulfonyl imides and lithium aluminates. Future prospect for studies of new lithium electrolyte salts is given.
