METHOD FOR PRODUCING SOLID ELECTROLYTE THIN FILMS FOR LITHIUM ION BATTERIES

摘要

A method of manufacturing a solid electrolyte thin film in a fully solid lithium ion battery comprising the steps of: a) Providing a possibly conductive substrate layer, optionally covered with an anode or cathode layer b) depositing a thin electrolyte layer by electrophoresis, from a suspension of particles of electrolyte material, onto said substrate and / or said anode or cathode layer previously formed, c) drying of the layer thus obtained, d) Densification of the thin electrolyte layer obtained in the preceding step by mechanical compression and / or thermal sintering.
