Abstract: The present technology relates to a coating material comprising at least one branched or linear unsaturated aliphatic hydrocarbon having from 10 to 50 carbon atoms and having at least one carbon-carbon double or triple bond for use in electrochemical applications, particularly in electrochemical accumulators such as all-solid-state batteries. The present technology also relates to coated particles comprising said coating material and processes of manufacturing the same. Also described are electrode materials, electrodes, electrolytes, current collector coating materials and current collectors comprising said coated particles and their use in electrochemical cells, for example, in electrochemical accumulators, particularly in all-solid-state batteries.

Abstract: The present technology relates to inorganic compounds having an argyrodite-type structure based on an alkali metal obtained by a preparation process comprising a step of grinding the sulfide of the alkali metal, the sulfate of the alkali metal, phosphorus pentasulfide and a halide of the alkali metal. Also described are electrode materials, electrodes, electrolytes comprising said inorganic compound having an argyrodite-type structure and their uses in electrochemical cells, for example, in electrochemical accumulators, particularly in all-solid-state batteries.
