PROCESS FOR MANUFACTURING DENSED INORGANIC LAYERS USED AS ELECTRODES AND / OR ELECTROLYTES FOR LI-ION MICROBATTERIES, AND DENSED INORGANIC LAYERS THUS OBTAINED

摘要

A method of manufacturing a dense layer, comprising the following steps: supplying a substrate and a suspension of non-agglomerated nanoparticles of material P; depositing a layer, on said substrate, from said suspension; drying the layer thus obtained; densification of the dried layer by mechanical compression and / or heat treatment; said method being characterized in that the suspension of non-agglomerated nanoparticles of material P comprises nanoparticles of material P having a size distribution, said size being characterized by its value of D50, such that: - the distribution comprises nanoparticles of material P with a first size D1 between 20 nm and 50 nm, and nanoparticles of material P with a second size D2 characterized by a D50 value at least five times lower than that of D1; or the distribution has an average size of the material P nanoparticles of less than 50 nm, and a standard deviation to average size ratio greater than 0.6.
