| titleOfInvention | A kind of solid-state lithium ion battery and preparation method thereof |
| abstract | The invention relates to a solid-state lithium ion battery and a preparation method thereof, and belongs to the technical field of lithium ions. The battery of the present invention includes a battery core, which is formed by superimposing an integrated positive electrode sheet and an integrated negative electrode sheet and then hot pressing; the positive electrode active material layer of the positive electrode sheet and the negative electrode active material layer of the negative electrode sheet both contain ion conductive polymers; The ion-conductive polymer in the positive electrode active material layer is selected from one of polyacrylonitrile, polyvinylidene fluoride, vinylidene fluoride-hexafluoropropylene copolymer, and a polymer with active groups in the main chain and side groups connected to the main chain. One or any combination; the active group is selected from one or more groups in fluorine, cyano, and benzene ring-containing groups; the ion conductive polymer in the negative active material layer is polycarbonate and/or contains polyether segments of polymers. The battery of the invention has positive and negative electrodes matched with different ion conductive polymers, which can avoid the occurrence of side reactions related to the polymer in the charging and discharging process, improve the cycle performance of the solid-state lithium ion battery and reduce the impedance. |
