Abstract

The invention relates to the technical field of lithium batteries, and provides an ion / electron common conductor film and a preparation method thereof, which successfully synthesize an N-doped LiAlO2 film through reactive sputtering in an N2 atmosphere. Doped N replaces a part of O with a three-coordination structure in a molecule, a cross-linked network structure is formed through induction, and a weak binding force site is provided for transition of Li+. The prepared ion / electron common conductor film has high ionic conductivity and electron conductivity, and can completely replace a conductive additive or reduce the addition amount of different conductive additives in a solid-state battery. Based on the performance requirements of different solid-state batteries, the preparation requirements of the solid-state batteries with requirements on ionic conductivity and electronic conductivity can be met. The invention also relates to an electric vehicle with the solid-state battery.

Description

【Technical field】 [0001] The invention relates to the technical field of lithium batteries, in particular to an ion / electronic co-conductor thin film and a preparation method thereof, a solid-state battery and an electric vehicle. 【Background technique】 [0002] With the development of micro intelligent terminals, electric vehicles and other fields, the demand for all-solid-state batteries with high safety and high energy density is becoming increasingly urgent. Due to the potential of all-solid-state batteries to enable Li metal anodes, tremendous efforts have been made to study and stabilize the Li metal-solid electrolyte interface. In this field, a large number of studies have confirmed the interface stability of solid-state electrolytes and lithium metal anodes, such as LLTO, crystalline and amorphous sulfides, polymers and organic-inorganic composite solid-state electrolytes, and LiPON. However, despite the remarkable progress in combining Li metal with solid electroly...
