| titleOfInvention | A kind of lithium battery and preparation method thereof |
| abstract | In order to overcome the problems of poor safety performance of ordinary liquid electrolyte lithium batteries in the prior art, insufficient charge and discharge performance and high cost of gel or solid electrolyte lithium batteries, the present invention provides a lithium battery, comprising a battery casing and a battery located in the casing. A positive plate, a negative plate, a separator and an electrolyte in the body; the electrolyte contains a polymer lithium salt and an electrolyte; at least one of the positive plate, the negative plate and the separator contains both a Lewis acid and the polymer lithium salt; polymer lithium The salt includes a polymer segment, an anion and a cation connected to the polymer segment; the anion contains one or more of carboxylate, sulfonate, phosphate, and sulfate; the cation is lithium ion; Lewis acid is soluble in all salts. In the electrolyte solution, the mass concentration of the Lewis acid in the electrolyte solution is 0.5% or less. Meanwhile, the present invention also provides a preparation method of the above-mentioned lithium battery. The lithium battery provided by the invention can greatly improve the safety without reducing the charging and discharging performance, and has low cost. |
