Abstract (en)

[origin: CA3228241A1] The present technology concerns modifying the surface of an electrode film with a succession of thin layers, each with a thickness for example of 15 microns or less, with the first thin layer comprising an inorganic compound (such as a ceramic) in a solvating polymer, the inorganic compound being present in the first thin layer at a ratio by mass of inorganic compound to solvating polymer in the range from about 1:20 to about 20:1. Electrochemical cells comprising the modified electrodes are also described, as are secondary batteries comprising them.
