An electrolyte for a lithium-ion battery and a lithium-ion battery. The electrolyte for a lithium-ion battery comprises a non-aqueous organic solvent, a lithium salt, and an electrolyte additive. The additive is selected from compounds of formula 1, wherein R1 is selected from unsaturated alkyls having three to six carbon atoms, and R2 is selected from alkylenes having two to five carbon atoms. Because the molecular structure of the additive comprises both unsaturated carbon-carbon bonds and cyanos, polymerization can occur on an electrode surface to form a compound containing multiple cyanos. The compound can be complexed with metal ions on a surface of a cathode material, thereby inhibiting electrolyte decomposition on an electrode surface to improve high-temperature storage and cyclability of a battery. 

Electrolyte for lithium-ion battery and lithium-ion battery

Disclosed is a lithium ion battery non-aqueous electrolyte and a lithium ion battery, in which the electrolyte comprises: a non-aqueous organic solvent, a lithium salt and an additive, said additive comprises: a compound represented by the structural formula 1 and a compound represented by the structural formula 2, in which R is an alkyl selected from an alkyl group having 1 to 4 carbon atoms, the ratio of the content of the compound represented by the structural formula 1 to the total mass of the lithium ion battery non-aqueous electrolyte is 0.1% to 2%, and the ratio of the content of the compound represented by the structural formula 2 to the total mass of the lithium ion battery non-aqueous electrolyte is less than 0.5%.
