Recycling and Reuse of Cathode Material of Waste Ternary Lithium-Ion Power Battery

Since the commercialization of lithium-ion battery, lithium-ion battery has been widely used in mobile phone, computer, cameras and other electronic products with its high energy rate, light weight, long service time and many other advantages. But the recycling of the cathode materials of the waste ternary lithium-ion power battery has become an increasingly serious problem. Therefore, the recycling and reuse of the cathode materials of the waste ternary lithium-ion power battery was studied in this paper. First of all, the structure and composition of lithium-ion battery was introduced, and then the pretreatment and heat treatment of the waste ternary lithium-ion power battery was discussed. Finally, the recovery process of the cathode material was introduced in detail. The test results show that the recycling and reuse of the cathode material of the waste three ternary lithium-ion power battery is more practical and reasonable, which can better meet the recycling requirements of battery cathode materials, so the method has very strong practical value.
