| description | The invention belongs to the field of lithium ion batteries, and discloses a method for realizing a high-performance all-solid-state lithium ion battery by constructing a self-sacrifice reducing phase interface and an application of the high-performance all-solid-state lithium ion battery. The creation point of the method is that the surface of the lithium cobalt oxide positive electrode material is reduced by using reducing elementary substances (sulfur elementary substances, selenium elementary substances and carbon elementary substances) to construct a self-sacrifice reducing phase interface layer, so that the serious interface reaction between the solid-state battery positive electrode material and an electrolyte is well solved. The lithium cobalt oxide positive electrode material treated by the method shows good long cycle stability and excellent rate capability in an all-solid-state lithium ion battery based on sulfide electrolyte, and a new thought is provided for a modification method of a solid-state |
