Proposed are a method and a system for separating a cathode material of a waste lithium secondary battery using an oxidation reaction of an anode material and a reduction reaction of the cathode material. When lithium is heated to a level where lithium can undergo an explosive reaction using the low-temperature pyrolysis system, the binder, the electrolyte, and the separator contained in the waste lithium secondary battery are gasified into syngas by the explosive reaction of lithium and the resulting syngas is removed. The reduction reaction of the cathode material and the oxidation reaction of the anode material are promoted by the continuous explosive reaction of lithium and the stirring action of the spiral. As a result, the black powder and the current collector mixture are extracted. Therefore, it is possible to improve the recovery rate of valuable metals to more than 97%, thereby improving recycling efficiency.

The present invention relates to separation and recovery of metals from ground alkaline batteries using anode mud (zinc electrolysis waste) and other manganese and zinc containing materials. The material commonly referred to as alkaline black (AKB) is solubilized into sulfate media and the manganese to zinc ratio is adjusted. The solution containing metals is processed using crystallization and ion exchange methods to produce manganese sulfate and zinc sulfate solutions for several possible applications.

The present invention relates to a method of simultaneously recovering cobalt (Co) and manganese (Mn) from lithium-based BATTERY, and more particularly, to a method that is capable of simultaneously recovering cobalt and manganese from lithium-based BATTERY, i.e., recycled resources that contain large amounts of cobalt and manganese, with high purities using multistage leaching and electrowinning methods. According to the method of the present invention, cobalt and manganese can be simultaneously recovered from lithium-based BATTERY as recycled resources, and a recovery method that is cost-effective compared to conventional methods can be provided.
