| titleOfInvention | A kind of preparation method of flame retardant gel electrolyte lithium ion battery and lithium ion battery |
| abstract | The invention discloses a preparation method of a flame-retardant gel electrolyte lithium ion battery, comprising: step 1, reacting tetrabromobisphenol A with an alkenyl carboxylic acid whose number of C atoms is not more than 17 to generate alkenyl carboxylic acid tetrabromo The bisphenol A ester is washed with ethanol and dried; in step 2, the alkenyl carboxylic acid tetrabromobisphenol A ester and an initiator are added to the non-aqueous electrolyte to obtain a non-hydrogel electrolyte; wherein, the alkenyl carboxylic acid tetrabromo The bisphenol A ester is 1%-9%, and the initiator is 0.1%-1%; in step 3, the prepared non-aqueous gel electrolyte is added to the soft-pack lithium ion battery to form and polymerize. The invention also discloses the battery prepared by the above method. The preparation method of the flame-retardant gel electrolyte lithium ion battery of the present invention uses pure alkenyl carboxylate tetrabromobisphenol A as a polymerization monomer to form a gel polymer, which improves the safety of the battery and does not affect the conductivity The prepared flame-retardant gel electrolyte lithium-ion battery has good safety, high electrical conductivity and good cycle performance. |
