NOVELTY - The invention is a thin film solid electrolyte structure, which mainly includes: a solid electrolyte ion-transmitting layer and two graphene layers; in particular, the two graphene layers are directly overlaid on opposite sides of the solid electrolyte ion-transmitting layer. On both surfaces, and the graphene layer can be coated or plated to a predetermined thickness and molded on the surface of the solid electrolyte ion-transmitting layer, thereby forming a three-layer solid electrolyte structure; In addition, by virtue of the high energy density and strong cycling characteristics of the solid electrolyte, the cycling and service life of the battery can be improved, and the graphene layer can improve the situation where the interface impedance between the solid electrolyte and the electrode is large, and promote the Accelerated migration of electric ions at the positive or negative electrode will greatly improve the overall conductivity and storage of the battery, and will also result in higher thermal stability and safety.
