(EN) Multiphase electrolyte film for solid-state battery, preparation method of multiphase electrolyte film and all-solid-state lithium battery
(ZH) 一种固态电池用复相电解质薄膜及其制备方法以及全固态锂电池
要約
(EN) The invention relates to the technical field of lithium batteries, and particularly relates to a multiphase electrolyte film for a solid-state battery, a preparation method of the multiphase electrolyte film and an all-solid-state lithium battery. The multiphase electrolyte film for the solid-state battery comprises at least two solid electrolyte single-layer diaphragms, and each solid electrolytesingle-layer diaphragm is prepared from the following raw materials in parts by weight: 30%-70% of solid electrolyte particles, 8%-15% of a binder, 4%-12% of a plasticizer, 0.2%-2% of a dispersing agent and 17.8%-41% of a solvent. And the solid electrolyte particles are lithium-containing active fast ion conductors or inert inorganic nonmetals. The preparation method comprises the following steps: S1, preparing a slurry; S2, carrying out slurry forming; S3, casting to form a film; S4, mixing and laminating; S5, carrying out hot pressing; and S6, carrying out degreasing heat treatment. The multiphase electrolyte film for the solid-state battery can be used for an all-solid-state lithium battery and has the advantage of high mechanical strength; and in addition, the preparation method disclosed by the invention has the advantages of a simple process and convenience in industrial mass production.
