Abstract
The invention discloses a method of preparing a gel polymer lithium ion battery, comprising the following steps: solving P(VDF-HFP) in organic solvent, and then adding P(VDF-HFP) nonsolvent to obtain mixed P(VDF-HFP) solution; spreading the mixed P(VDF-HFP) solution on the diaphragm or the positive electrode plate and the negative electrode plate of the lithium ion battery to volatilize the solvent of the mixed P(VDF-HFP) solution and form a composite porous film on the diaphragm or the positive electrode plate and the negative electrode plate of the lithium ion battery; assembling the positive electrode plate and the negative electrode plate with the diaphragm of the lithium ion battery, and injecting liquid electrolyte in to as assembled electrical core; and heating and baking the electrical core to make the composite porous film and the liquid electrolyte form gel to obtain the gel polymer lithium ion battery. The method of preparing the gel polymer lithium ion battery has simple process, low cost and wide application range and ensures that the produced composite porous film has high liquid absorption rate and stable structure and the gel polymer lithium ion battery has good cycling performance and conducting performance.
