Abstract
The application belongs to the field of lithium batteries, and particularly relates to a solid-state battery system and a preparation method thereof. The solid-state battery system comprises a composite electrolyte cathode and a porous anode; the composite electrolyte cathode is a composite structure in which a connecting framework is constructed on a high-nickel NCM-based cathode, and a solid-state electrolyte film is fixed by the connecting framework to realize the compounding of the cathode and the electrolyte. The application matches the setting mode of "no anode" through the in-situ construction mode of "core-shell-skeleton integration", greatly improves the active proportion of the cathode, solves the problem of low energy density of traditional solid-state batteries, and greatly widens the wide-temperature-range working performance of the solid-state battery in a bidirectional manner.
