Abstract

The invention relates to a preparation method of an all-solid-state metal ion battery. The preparation method comprises steps as follows: a substrate is provided; at least two laminating units are formed on the substrate, and each laminating unit comprises a cathode film, an anode film and an inorganic solid-state electrolytic film arranged between the cathode film and the anode film; the laminating units are superimposed. The invention further relates to the all-solid-state metal ion battery comprising at least two laminating units superimposed on the substrate as well as an electric vehicle utilizing the all-solid-state metal ion battery. The battery prepared with the preparation method of the all-solid-state metal ion battery has the characteristics of nontoxicity, high safety, high energy density, high battery capacity, high charge-discharge capacity retention and the like.

Description

【Technical field】 [0001] The invention relates to the technical field of energy storage, in particular to an all-solid metal ion battery, a preparation method thereof, and an electric vehicle. 【Background technique】 [0002] Electric energy is the most common and most promising application form of clean energy. Energy storage technology is a key link in the adjustment and transformation of energy structure from traditional fossil energy to clean energy such as wind energy and solar energy.
