FIELD: electricity.SUBSTANCE: declared invention relates to the electrodes, electric power accumulation devices containing such electrodes and to methods of manufacture of electrodes and the electric power accumulation devices. Electrodes contain a current collector, a conductive mat and the first and second electrically active materials, and the first electrically active material has higher energy density, than the second electrically active material, and the second electrically active material has an ability to higher charging-discharging rate, than the first electrically active material. The conductive mat can provide a structural and conductive support for at least one of electrically active materials with high energy and high charging-discharging rate, meanwhile the conductive mat contains a porous grid from interconnected conductive fibres that provides stability of the fibrous mat against shift and rupture of the mat due to rupture strength of fibres.EFFECT: electrodes can be provisioned in various configurations and can be used in high-rate and high-energy electric power accumulation devices with ensuring of improved cyclic resource.15 cl, 21 dwg, 4 tbl |
