The present application provides an electrolyte that comprises a non-aqueous organic solvent and a lithium salt. The non-aqueous organic solvent contains chain carboxylic ester and cyclic carbonate that has a chemical structural formula containing a C=C double bond. The content of the cyclic carbonate having the chemical structural formula containing the C=C double bond is not larger than 1% in mass percentage in the electrolyte. The electrolyte can be used for a long time under the condition of high voltage, can be used in a lithium ion battery, can normally work for a long time under the condition that the working voltage is higher than 4.35 V and ensures the high-temperature property of a battery. |
