STRIPPING AGENT FOR SECONDARY BATTERY ELECTRODE MATERIAL AND METHOD OF TREATING SECONDARY BATTERY USING THE STRIPPING AGENT

摘要

An electrode of a secondary battery is treated to remove an electrode material adhering to the current collector of the electrode. The electrode is treated by exposing to a stripping agent, which is constituted as an aqueous solution containing at least one of an organic sulfonic acid and derivative thereof, and the electrode exposure to each other to strip the electrode material from the current collector constituting the electrode.
