METHOD FOR THE PRODUCTION OF THIN FILMS OF SOLID ELECTROLYTE FOR LITHIUM ION BATTERIES

摘要

The invention relates to a method for the production of a thin film of solid electrolyte in a totally solid lithium ion battery, comprising the steps of: a) obtaining a film of an optionally conductive substrate, optionally covered with an anode or cathode film; b) depositing a thin film of electrolyte by means of electrophoresis, from a suspension of particles of electrolyte material, onto the substrate and/or the anode or cathode film already formed; c) drying the resulting film; and d) densifying the thin electrolyte film obtained during the previous step by means of mechanical compression and/or thermal treatment.
