CHARGE ACCUMULATOR, METHOD OF ITS MANUFACTURING, METHOD FOR MANUFACTURING OF ELECTROCONDUCTIVE STRUCTURE FOR CHARGE ACCUMULATOR, MOBILE ELECTRONIC DEVICE USING CHARGE ACCUMULATOR AND MICROELECTRONIC DEVICE CONTAINING CHARGE ACCUMULATOR Russian patent published in 2015 - IPC H01G4/05 H01G11/24 

FIELD: electricity.

SUBSTANCE: invention suggests a double-layer capacitor (EDLC), which has the first (110) and second (120) electroconductive structures separated from each other by a separator (130). At least one of the two above electroconductive structures includes porous structure containing a set of channels (111, 121) having an opening at surface of the porous structure, at that each of the channels has an opening (112, 122) at surface (115, 125) of the porous structure. According to another embodiment the charge accumulator includes a set of nanostructures (610) at the substrate (605), electrolyte (650) contacting at least some of nanostructures physically, material (615) with dielectric permeability of at least of 3.9 is placed between the electrolyte and nanostructures. The nanostructures in the claimed device are made of silicium, silicium-germanium, silicon carbide, aluminium, tungsten, copper. The invention also suggests the method for manufacturing of electroconductive structure and method for manufacturing of the charge accumulator.

EFFECT: reducing overall dimensions and weight of the accumulator, increasing square area of the electrode surface and capacitance.
