Abstract (en)

[origin: CA3166945A1] The present technology relates to the modification of the surface of an electrode comprising a thin layer, for example of 10 microns or less, of an inorganic compound (such as a ceramic) in a solid polymer, the inorganic compound being present in the thin layer at a concentration of between approximately 40% and approximately 90% by mass. Also described are the electrodes comprising the modified film, a component comprising the electrode and a solid electrolyte, and the electrochemical cells and storage batteries comprising same.
