  • Secondary battery and method for charging and discharging secondary battery
    Patent number: 9711824
    Abstract: A secondary battery that has an electrode active material mainly composed of a low-molecular-weight multi-electron organic compound that has two or more electrons to be involved in a battery electrode reaction, and a solvent for an electrolyte solution that contains a sulfone compound. Apart of the electrode active material is dissolved in and reacted with the electrolyte solution at the first charge and discharge, thereby oligomerizing a part of the electrode active material.

  • SECONDARY BATTERY AND METHOD FOR PRODUCING SECONDARY BATTERY
    Publication number: 20150243992
    Abstract: A secondary battery that includes a positive electrode active material layer, which is mainly composed of an organic compound having a multi-electron system, on a surface of a positive electrode current collector. The surface of the positive electrode active material layer is covered by an ion-conducting thin film that selectively transmits lithium ions. A positive electrode is composed of the positive electrode current collector, the positive electrode active material layer, and the ion-conducting thin film.

  • ELECTROLYTE SOLUTION FOR DYE SENSITIZED SOLAR CELL, AND DYE SENSITIZED SOLAR CELL USING SAME
    Publication number: 20120301992
    Abstract: It is to provide an electrolyte solution for a dye sensitized solar cell that does not generate a gas, can be used in a wide temperature range, and is excellent in durability. The electrolyte solution contains a chain sulfone compound represented by formula (1) as a solvent. (In the formula, R1 and R2 each independently represent an alkyl group having from 1 to 12 carbon atoms, which may be partially substituted by a halogen, an alkoxy group or an aromatic ring, an alkoxy group, or a phenyl group.
