Abstract
Provided is a non-aqueous electrolyte, comprising a solvent, an electrolyte salt and a compound represented by structural formula 1: wherein, A, G and X are each independently selected from a cyclic sulfate group and its derivatives, a cyclic sulfonate group and its derivatives, a cyclic sulfite group and its derivatives or a group D; one or none of A, G and X is selected from the group D, and the group D is selected from a C1-C4 alkyl group, a C1-C4 unsaturated hydrocarbon group, a C1-C4 haloalkyl group, a C1-C4 nitrile group, a C1-C4 ether group or a C1-C4 ketone group. The application also provides a battery comprising the non-aqueous electrolyte. By adopting the above compound as an additive for the non-aqueous electrolyte, the film-forming quality of the surfaces of positive and negative electrodes can be effectively improved, and thus the battery performance is improved.
