| titleOfInvention | Electrolyte for improving high-temperature property of lithium manganate battery |
| abstract | The invention discloses electrolyte for improving a high-temperature property of a lithium manganate battery, and belongs to the technical field of electrolytes for lithium ion secondary batteries. The electrolyte comprises a nonaqueous organic solvent, lithium salt and a cathode film formation additive; and the electrolyte is characterized by further comprising a cyanophenyl fluoride additive and a fluorocarbon surfactant. In the primary charging process, a layer of protection film is formed on the surface of an anode by cyanophenyl fluoride, the decomposing and gas forming of the electrolyte on the surface of the anode are reduced, the dissolving of Mn<2+> ions in positive active materials can be restrained in subsequent processes of charging and discharging, and the high-temperature property of the lithium manganate battery is improved; and by virtue of adding the fluorocarbon surfactant, the surface tension of the electrolyte of the lithium ion secondary battery is reduced, the adsorption and infiltration of a positive sheet, a negative sheet and a membrane on the electrolyte are effectively improved, the stable and uniform state of the electrolyte in the battery is quickly achieved, and the cycle life of the battery can be prolonged. By utilizing the cyanophenyl fluoride additive and the fluorocarbon surfactant, the lithium manganate battery has an excellent high-temperature cycle property. |
