TL;DR: In this paper, a new type redox battery was developed using ruthenium complexes in organic electrolyte solution as the electrode active materials, which had an open circuit voltage of 2.6 V and a discharge current of 5 mA cm−2 (at a smooth carbon electrode).

TL;DR: In this paper, physicochemical properties of the mixed solvents of propylene carbonate and 1,2-dimethoxyethane dissolving various salts have been measured at 30/degree/C, in order to clarify the mixing effect of the organic electrolytes for high energy density batteries.

TL;DR: In this article, solid polymer electrolytes consisting of complexes of poly(ethylene oxide)grafted poly(methyl)methacrylate (PEO•PMMA) and tetraalkylammonium salts [tetrabutylmonium perchlorate, tetraethylammoniam perchlorates, and tetrasetraethyammonium tetrafluoroborate (TEABF4)] have been investigated for electric double-layer capacitors with activated carbon fiber cloth electrodes.

TL;DR: In this article, the effect of particle size of ultrafine platinum particles, which were prepared by vacuum evaporation onto a glassy carbon rod, on the electrochemical oxidation of methanol and formic acid has been examined by a cyclic voltammetry.

TL;DR: In this paper, the effects of the size of the platinum particles on the hydrogen electrode reaction were examined in an aqueous solution of sulfuric acid by use of a Pt/GC model catalyst electrode which was prepared by vacuum evaporation of platinum onto a flat surface of a glassy carbon rod support.
