COMPOSITE SOLID ELECTROLYTE BASED ON IONIC ORGANIC SALTS OF SUBSTITUTED AMMONIUM WITH BUTYL AND METHYL RADICALS AND A HETEROGENEOUS ADDITION OF NANODIAMONDS Russian patent published in 2023 - IPC H01M6/18 H01M10/565 H01G11/56 

FIELD: energetics.

SUBSTANCE: electrolytic solid composite materials based on organic salts of substituted ammonium with butyl and methyl radicals, which can be used in various electrochemical devices (supercapacitors, batteries, etc.). During the interaction of salt ions with the surface functional layer of nanodiamonds, an interfacial layer is formed, which has an increased content of defects, which is the cause of increased conductivity. The maximum concentration of such a layer in the bulk of the composite is achieved with a composition in which the volume fractions of the ionic salt and nanodiamonds are approximately equal.

EFFECT: development of a solid composite electrolyte based on organic salts of substituted ammonium with butyl and methyl radicals, characterized by an increased value of specific conductivity in the medium temperature region (50-150°C) and microhardness.
