ADDITIVE FOR NON-AQUEOUS ELECTROLYTE AND SECONDARY BATTERY USING THE SAME

摘要

A secondary battery is provided to improve the charge and discharge efficiency of a battery through forming a SEI film by using a silyl amide-based compound as electrolyte additives. An electrolyte for a secondary battery comprises an electrolyte salt and electrolytic solvent. The electrolyte comprises a silyl amide-based compound which forms a solid electrolyte interface(SEI) film on a negative electrode of a secondary battery by an electrical reduction.
