Abstract
An electrode film of an all-solid-state battery, an all-solid-state battery, and an electrode of an all-solid-state battery, which are fabricated by a process that includes thermally consolidating an electrode film by sintering at a temperature that does not exceed a predetermined threshold of a lowest melting temperature between an anode material and an cathode material.
Claims18
A method for manufacturing an all-solid battery made of thin films, comprising:
- (a) depositing at least one layer of anode material on a first conductive substrate selected from a group formed by a metal sheet, a metal strip, a metallized insulating sheet, a metallized insulating strip, and a metallized insulating film, said first conductive substrate or conductive elements thereof to act as an anode current collector;
- (b) depositing, before or after depositing the at least one layer of anode material, at least one layer of cathode material on a second conductive substrate selected from a group formed by a metal sheet, a metal strip, a metallized insulating sheet, a metallized insulating strip, and a metallized insulating film, said second conductive substrate or conductive elements thereof to act as a cathode current collector;
- (c) depositing at least one layer of solid electrolyte material on the deposited at least one layer of anode material or on the deposited at least one layer of cathode material;
- (d) depositing, after depositing the at least one layer of solid electrolyte material, a layer of a solution of an ionic conductive material composed of at least one lithium salt on the deposited at least one layer of anode material and/or the deposited at least one layer of cathode material;
- (e) drying the deposited layer of the solution of the ionic conductive material to obtain a layer of an ionic conductive material, the thickness of the layer of the solution of the ionic conductive material being less than 2 μm;
- (f) successively stacking, after drying the deposited layer of the solution of the ionic conductive material, the deposited at least one layer of anode material, face on face, with the deposited at least one layer of cathode material;
- and
- (g) conducting a heat treatment and/or mechanical compression on the stack to obtain the all-solid battery.
