ELECTROLYTE AND LITHIUM-ION BATTERY CONTAINING THE SAME

The present application relates to the technical field of lithium-ion batteries and, specifically, relates to an electrolyte and a lithium-ion battery containing the electrolyte. The electrolyte of the present application comprises a lithium salt, an organic solvent and additives that include additive A, additive B and at least one of additive C and additive D; in which, the additive A is a cyclic sultone; the additive B is a cyclic sulfate; the additive C is a silane phosphate compound and/or a silane borate compound; and the additive D is a fluoro-phosphate salt. The battery of the present application has low gas production at high temperature, high capacity retention rate and high power at low temperature as a function of synergistic effects of additives.
