The activated porous carbon-based materials of ultrafine fibers in high energy storage — •Svetlana Klimova — Saratov State University, Department of Electrospinning, 410012 Saratov, Russia

The design of the accumulating electrode material is the ultra-light material based on a polymeric fiber coated with a porous layer of graphene which is deposited by magnetron sputtering and is inert to the polymer electrolyte. To create ultraporous electrode materials with pore sizes of 150-200 nm or less and a specific surface area of 1,500 - 2,000 m2 / g, the development of the electrospinning method of the solid polymer electrolyte with or without filler having ion conductivity is 5 times higher than that of the liquid electrolytes was carried out. The graphene film possessing a columnar structure with high surface area was deposited on the fiberous surface. The strongly vertical carbon nanotubes to the substrate surface with length and diameter sizes about 80 nm and with a packing density on the sample surface about 4-5 nanotubes per 1 mkm2 was obtained. The values of the stored energy in the "active electrode" is suspected up to 5-10 W*hour / kg.
