Beschreibung
Zusammenfassung:	Disclosed is a method for recovering and processing a retired battery electrode plate. The method includes disassembling a retired battery to obtain an electrode plate, energizing two ends of the electrode plate until a binder on the electrode plate is heated and melted, and then separating out an electrode material and a current collector, and when the electrode plate is a negative electrode plate, ball milling the separated electrode material, winnowing the ball-milled material to obtain graphite, subjecting the graphite to an alkali treatment, adding the graphite, which has been subjected to the alkali treatment, and an aggregate to softened asphalt, and stirring same to obtain conductive asphalt. The two ends of the electrode are energized, such that the binder is melted into liquid to flow out of the current collector, and the electrode material is stripped off the electrode plate.
