INTEGRIERBARE FESTSTOFFZELLE UND VERFAHREN ZU IHRER HERSTELLUNG.

摘要

This invention relates to a process for producing a solid state battery successively comprising, superposed between two metallic contact elements, a layer or thin film of an alkali metal such as lithium, constituting a source of ions, a layer or thin film of a superionic solid electrolyte and a layer or thin film of a layered intercalation compound capable of inserting ions issued from the alkali metal film. The lamellae of the film of layered compound are oriented so that their c-axis is substantially parallel to the surface of the solid electrolyte. The process consists essentially in making the layer or thin film of layered compound by direct grafting on the film which is to serve as substrate therefor, on which is initially impressed a grating which conditions the nucleation starting the crystal growth by means of the techniques of molecular beam deposition. The invention also relates to a battery made in accordance with this process.
