  • Lithium-aluminum hydrotalcite-based solid electrolyte film working at room temperature, preparation method thereof, and lithium battery including same
    Patent number: 12278334
    Abstract: Disclosed are a lithium aluminum hydrotalcite-based solid electrolyte film, a preparation method and use thereof, and a lithium battery including the same. The lithium aluminum hydrotalcite-based solid electrolyte film includes: a solid electrolyte film substrate formed by an organic polymer, and a lithium salt and a lithium aluminum hydrotalcite uniformly dispersed in the solid electrolyte film substrate, wherein the lithium aluminum hydrotalcite has a content of 50 wt % to 80 wt %, based on a total mass of the solid electrolyte film substrate after removal of the lithium salt; and the organic polymer includes one or more selected from the group consisting of polyethylene glycol diacrylate, polyethylene oxide, polypropylene carbonate, and polyvinylidene fluoride-hexafluoropropylene copolymer.
    Type: Grant
