Title:
LITHIUM BATTERY ELECTROLYTE
Document Type and Number:
WIPO Patent Application WO/2019/000583
Kind Code:
A1
Abstract:
Disclosed is a lithium battery electrolyte. The lithium battery electrolyte is composed of the following raw materials in parts by weight: 7-13 parts of dimethyl sulfoxide, 5-15 parts of ethanolamine sulfate, 17-32 parts of nanometer titanium dioxide, 3-9 parts of polyvinylpyrrolidone, 5-11 parts of potassium bistrifluoromethyl sulfonimide, 2-4 parts of lithium hexafluorophosphate, 3-5 parts of benzoic acid, 2-8 parts of sodium carboxymethyl cellulose, 0.5-2 parts of sodium polyaspartate, and 1-2 parts of N,N-dimethyl-p-phenylenediamine oxalate. The lithium battery electrolyte provided in the present invention inhibits the capacity attenuation of the battery at low temperatures, and can reduce the amount of gas generated by the electrolyte under high-temperature conditions, effectively preventing battery expansion and improving the high-temperature performance of the battery.
