MULTICHANNEL ELECTRODE Russian patent published in 2021 - IPC H01G4/10 H01G4/32 H01B3/00 B82B3/00 

FIELD: microelectronics.

SUBSTANCE: invention relates to the field of microelectronics and can be used in systems generating or storing electrical power (capacitors, supercapacitors, current sources). The multichannel electrode includes a substrate of an inert dielectric material, with a honeycomb structure formed by tubular microchannels, a submicron current-conducting coating of an inert metal, e.g., silver, applied to the surface of the substrate and the surface of the microchannel walls, an active layer of a superionic conductor in form of nano- and submicro-sized particles, and a current collector applied to the substrate. The technical result is achieved due to the fact that the active layer of the superionic conductor is applied directly to the current-conducting coating of the microchannel walls and comprises particles of a solid solution of a composition K_xM_yTi_(8-y)O₁₆ with a hollandite structure, wherein M is at least one transition metal.

EFFECT: increased specific electrical capacity of the electrode, retained after repeated charge-discharge cycling, and thus, increased specific power stored by the electrode while being connected to an electrical circuit comprised in an electrical power accumulator.
