A method for efficiently recycling waste ternary lithium ion battery positive electrode material by using pome fruit green solvent

Abstract

The present application belongs to the technical field of lithium ion battery recycling, and particularly relates to a method for efficiently recycling positive electrode materials of waste ternary lithium ion batteries by using green solvents made of pome fruit. The method uses apples as raw materials to prepare green solvents, which are used to replace corrosive acids in the recycling process, and are used to dissolve and recycle metal ions of nickel, cobalt, manganese and lithium in the positive electrode material of waste ternary lithium ion batteries, namely nickel-cobalt-manganese lithium acid, thereby improving the recovery rate of high-value metals such as nickel, cobalt and manganese. The lithium ion battery recycled from the recycled metals has good electrochemical performance and can meet the demand of practical application. The method is green, simple, efficient, low-cost and easy to operate, and conforms to the concept of sustainable development in China at present, and has very high application value.
