Solid-state electrolyte and solid-state battery containing same

The invention discloses a solid-state electrolyte and a solid-state battery containing the same. According to the solid-state electrolyte and the solid-state battery containing the same, a novel polymer material (crown ether organic covalent skeleton structure material (COFs)) is synthesized as a modification layer to modify two sides of an inorganic solid-state electrolyte and/or an organic solid-state electrolyte in situ; and a final solid-state battery structure is a positive plate-polymer-inorganic solid electrolyte sandwich-like structure and/or an organic solid electrolyte-polymer-negative plate sandwich-like structure. The modification method provided by the invention can effectively improve the interface performance between a solid electrolyte and an electrode in situ, so that a prepared polymer solid electrolyte coating can significantly increase the transmission channel of lithium ions on a positive electrode/inorganic ceramic chip/negative electrode interface, and therefore, the transmission impeda
