  • SURFACE-MODIFIED ELECTRODES, PREPARATION METHODS AND USES IN ELECTROCHEMICAL CELLS
    Publication number: 20230060872
    Abstract: 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 between about 40% and about 90% by weight. Also described are electrodes comprising the modified film, a component comprising the electrode and a solid electrolyte, and the electrochemical cells and accumulators comprising same.

  • COPOLYMERS OF ESTER AND ETHER UNITS, PROCESSES FOR PRODUCING SAME AND USES THEREOF
    Publication number: 20210380745
    Abstract: The present technology relates to a polymer comprising at least one ester repeating unit and one ether repeating unit for use in an electrochemical cell, particularly in electrochemical accumulators such as lithium batteries, sodium batteries, potassium batteries and lithium-ion batteries. More specifically, the use of this polymer as a solid polymer electrolyte (SPE), as a matrix for forming gel electrolytes, or as a binder in an electrode material are also contemplated.
