| titleOfInvention | Self-supporting polymer film material for lithium ion secondary battery and preparation method thereof |
| abstract | The invention discloses a self-supporting ionic polymer membrane material, a preparation method thereof and a lithium secondary battery, and belongs to the technical field of lithium battery manufacturing. The invention provides an ion polymer membrane material with an interpenetrating network structure. The cross-linked polymer is formed by mutually and continuously interpenetrating networks obtained by respectively cross-linking a cross-linked polymer I with sulfonate groups on the surface and a cross-linked polymer II. The membrane is a compact membrane without pores, and the diaphragm has no obvious thermal contraction when the battery is overheated. In addition, the interpenetrating ion conduction path is formed between the colloid particles after the ion polymer film with the interpenetrating network structure absorbs the electrolyte, and the colloid particle structure is still maintained after the ion polymer film absorbs the electrolyte solution or the solvent, so that the ion conduction tortuosity is increased by the close packing structure of the colloid particles, and the electronic insulation performance of the electrolyte film is improved. Meanwhile, the existence of the interpenetrating network structure improves the mechanical property of the ionic polymer membrane and realizes the unification of the mechanical property and the electrochemical property of the ionic polymer membrane. |
