摘要： A flexible electrode comprises an activated cotton textile composite comprising activated carbon fibers, nickel sulfide nanoparticles and graphene and a process for making the flexible electrode. The process may comprise preparing a cotton textile containing Ni(NO3)2. Then, the cotton textile containing Ni(NO3)2 may be heated at a first temperature to produce an activated cotton textile composite comprising activated carbon fibers, nickel nanoparticles and graphene. The activated cotton textile composite may be then treated with sulfur to produce an activated cotton textile composite comprising activated carbon fibers, nickel sulfide nanoparticles and graphene. The nickel sulfide particles may be NiS2 nanoparticles in a form of nanobowls, and distributed on a surface and inside the activated carbon fibers. The activated carbon fibers and the nickel sulfide nanoparticles may be coated with graphene. Banana peels may be activated and treated with the similar processes to form electrodes for both supercapacitor and battery applications.

摘要： An electrode having a planar electrode body with a plurality of hexagonally shaped through-holes formed therein. The planar electrode body is configured for use in a polar, protic, or aprotic solvent of a Hydro-Pyroelectrodynamic (“H-PED”) energy storage device. The electrode may be constructed using a method that includes applying a layer of graphene to an outer surface of the planar electrode body, and annealing the outer surface of the planar electrode body after the layer of graphene has been applied thereto.

摘要： An electric energy storage device has first and second conductor layers, a plastic sheet, a quantum dot, and positive and negative electrodes wherein the first and second conductor layers has surfaces coated with ionic or dipole material. The first conductor layer is stacked on top of the second conductor layer with a nanometer-scale interval and with the ionic material layer inbetween, forming a bilayer structure and a quantum heterostructure. Millions of bilayers are stacked together to form a multilayer structure. A positive electrode is attached to the first conductor layer and a negative electrode is attached to the last conductor layer, wherein the first and second conductor layers store electrical energy in the bilayer in a form of binding energy.

摘要： Provided is an electrode which gives an electric storage device that has high energy density and good cycle life. This electrode for an electric storage device is characterized by having an active material layer that contains: an electrode active material particle; and a paste-like conductive carbon that is derived from an oxidized carbon obtained by giving an oxidizing treatment to a carbon raw material with an inner vacancy and covers a surface of the electrode active material particle. The paste-like conductive carbon derived from the oxidized carbon is densely filled not only into a gap that is formed between the electrode active material particles adjacent to each other but also into a pore that exists on the surface of the active material particle, so that the electrode density is increased, thereby improving the energy density of the electric storage device. In addition, since the paste-like conductive carbon suppresses dissolution of the active material, the cycle characteristics of the electric storage device are improved.
