ORGANIC RADICAL SECONDARY BATTERY, CHARGE/DISCHARGE CONTROL METHOD OF THE ORGANIC RADICAL SECONDARY BATTERY, AND CHARGE/DISCHARGE CONTROL DEVICE OF THE ORGANIC RADICAL SECONDARY BATTERY

摘要

PPROBLEM TO BE SOLVED: To provide a secondary battery which is easy to detect the battery charging state. PSOLUTION: In the secondary battery equipped with a positive electrode capable of adsorbing and discharging anions, a negative electrode capable of adsorbing and discharging cations, and an electrolytic solution in which the cations and the anions are dissolved between the positive electrode and the negative electrode, at least one electrode active material of the positive electrode and the negative electrode contains two or more of radical compounds which differ in oxidation-reduction potential. According to this constitution, since it becomes possible to multi-stage the battery potential at the time of charge/discharge, it is possible to carry out detection of the battery charging state easily.
