A substrate treatment apparatus according to the present invention is provided with a first tank that stores treatment liquid for treating a substrate and a first path that returns the treatment liquid, which has spilled over from an upper part of the first tank, to a lower part of the first tank. A second path that branches from the first path, a measurement tank that stores the treatment liquid, which has flowed in from the second path, and a pressure measurement part that measures the pressure of the treatment liquid at a predetermined depth in the measurement tank in a state in which the treatment liquid spills over from an upper part of the measurement tank are provided. Therefore, techniques for highly precisely measuring the pressure of the treatment liquid used in treatment of substrates can be provided.

Substrate treatment apparatus and substrate treatment method

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 charging and discharging secondary battery

Provided is a battery having a high charging/discharging capacity density as compared with a conventional one. The battery () is characterized by comprising a positive electrode (), a negative electrode (), and an electrolytic solution interposed between the positive electrode () and the negative electrode () and formed by dissolving an electrolytic solution in a solvent, wherein the positive electrode () includes rubeanic acid or a rubeanic acid derivative as an active material and the solvent includes an ionic liquid. In the battery (), it is possible to neutralize, by anions present in the ions, positive charges generated when rubeanic acid or the rubeanic acid derivative is oxidized. Therefore, rubeanic acid or the rubeanic acid derivative can take three states from an oxidant to a reductant, so that a high charging/discharging capacity density can be obtained in comparison with a conventional one.

Battery containing rubeanic acid or derivative thereof as active material

An electrode active material has, as a main component, a mixture of an organic compound containing a rubeanic acid and cyanomethanesulfonylamide. The rubeanic acid is represented by the following general formula: In the formula, n indicates an integer between 1 and 20, and R-Rindicate hydrogen atoms, halogen atoms, or a prescribed substituent group such as a hydroxide group, a 1-3C alkyl group, an amino group, a phenyl group, a cyclohexyl group, or a sulfo group.
