METHOD FOR TREATING ACTIVE CARBON, TREATED ACTIVE CARBON, AND STORAGE BATTERY USING THE TREATED ACTIVE CARBON

摘要

PPROBLEM TO BE SOLVED: To provide a method for modifying active carbon so that the decomposition of an electrolyte is suppressed on a pore wall, active carbon obtained by such a treatment, and a storage battery which utilizes the active carbon and in which reduction of power output and capacity is suppressed over a long period of time. PSOLUTION: The present invention is embodied in a method for modifying a pore wall of active carbon. This treatment method comprises the steps of: (step S2) bringing active carbon into contact with an amine compound, a carboxyl group being adsorbed to the surface of the active carbon containing a pore wall; (step S3) immersing the active carbon which is brought into contact with the amine compound in an acid having a high viscosity; and (step S4) immersing the active carbon taken out of the acid in a treatment liquid having a low viscosity.
