A device and related method for producing electrical energy, in the form of current flowing in a load. The said method uses two solutions with different ionic concentration as energy source. The said device includes at least two electrodes immersed at least partially in a liquid contained in a cell. The method includes a plurality of phases. Among them, a phase in which the electrodes and are brought into contact with a first solution; a phase in which they are electrically charged; a phase in which they are brought into contact with a second solution; a phase in which at least a part of the accumulated charge is let flow through the load. The energy provided to the load is more than the energy used to charge the electrodes.

This invention relates to a capacitor electrode which includes porous layers made of a fiber and/or a whisker containing crystal tungsten oxides. The tungsten oxide fiber and/or whisker contain W18O49 as a main ingredient. The tungsten oxide fiber and/or whisker are made on a substrate. When manufacturing the capacitor electrode the substrate or its precursor is heated in vacuo or in an inactive containing a minute amount of oxygen, thereby completing the fiber and/or whisker.

Electrochromic salts. Electrochromic salts of dicationic viologens such as methyl viologen and benzyl viologen associated with anions selected from bis(trifluoromethylsulfonyl)imide, bis(perfluoroethylsulfonyl)imide, and tris(trifluoromethylsulfonyl)methide are produced by metathesis with the corresponding viologen dihalide. They are highly soluble in molten quarternary ammonium salts and together with a suitable reductant provide electrolyte solutions that are used in electrochromic windows.

摘要:
The invention is an electrochemical capacitor with its electrodes made on a conducting substrate with a layer of a redox polymer of the poly[Me(R-Salen)] type deposited onto the substrate. Me is a transition metal (for example, Ni, Pd, Co, Cu, Fe), R is an electron-donating substituent (for example, CH3O—, C2H5O—, HO—, —CH3), Salen is a residue of bis(salicylaldehyde)-ethylendiamine in Schiff's base. The electrolyte comprises of an organic solvent, compounds capable of dissolving in such solvents with the resulting concentration of no less than 0.01 mol/l and dissociating with the formation of ions, which are electrochemically inactive within the range of potentials from −3.0 V to +1.5 V (for example, salts of tetramethyl ammonium, tetrapropyl ammonium, tetrabutyl ammonium), and a dissolved metal complex [Me(R-Salen)]. The method of using the capacitor contemplates periodically alternating the connection polarity of the electrodes, causing the electrochemical characteristics of the electrodes to regenerate.
