Abstract
A method for the production of a battery includes at least production, against a substrate made of a material able to form an electrode, of at least one solid electrolyte layer, production of a first electrode in contact with the electrolyte, and thinning the substrate such that at least a remaining proportion of the substrate, in contact with the solid electrolyte layer, forms a second electrode.
Claims11
A method for producing a battery, the method comprising:
- producing, against a substrate made of a conductive or semi-conductive material able to form an electrode, at least one solid electrolyte layer;
- producing a first electrode in contact with the solid electrolyte layer;
- forming, in the substrate, an embrittlement zone by a technique of atom implantation or, alternatively, by a technique of diffusion of ions derived from the first electrode such that the embrittlement zone comprises one or more ionic and/or atomic species;
- thinning the substrate by separating along the embrittlement zone such that at least a portion of the substrate, which is in contact with the solid electrolyte layer, forms a second electrode, which has a thickness of less than or equal to approximately one tenth of an initial thickness of the substrate and less than 10 μm;
- and
- producing an electrically conductive material positioned against the first electrode and against the second electrode.
