Electrolyte additives for lithium-ion batteries under high-voltage operation
Abstract
A non-aqueous electrolyte for a lithium-ion battery comprises a lithium salt and an additive in an organic solvent. The additive comprises a di-substituted malonate silyl ester compound, in which the hydrogens of the malonate methylene group are replaced by substituents R1 (e.g., alkyl) and X (e.g., halogen). Each of the carboxylic acid groups of the malonate are esterified by a monovalent silyl group such as —Si(R4)3; or the two carboxylic acid groups are esterified by a single divalent silylene group such as —Si(R5)2— to form a ring therewith. Each R4 and R5 independently is alkyl, phenyl, or alkoxy; and each substituted-alkyl comprises an alkyl moiety substituted with one or more group selected from alkenyl, alkynyl, hydroxy, halogen, alkoxy, carboxylic acid, carboxylic ester, carboxylic amide, phenyl, sulfonic acid, and phosphonic acid.
