Experimental Study on Pyrolysis of Waste Lithium Battery Electrode Plates
As a secondary resource,waste lithium batteries contain enormous recycling value.Based on the pyrolysis properties of its main components,this paper conducts pyrolysis experiments on waste lithium battery electrode plates.The main influencing factors of the pyrolysis process of positive and negative electrode plates after the crushing and sorting of discarded lithium batteries include temperature,time,vacuum degree,and atmosphere.The experimental results show that a good pyrolysis effect can be achieved under vacuum and nitrogen atmosphere at a pyrolysis temperature of 400℃ and a pyrolysis time of 0.75 h,the yield of black powder is 75％～78％,and the recovery rate of major metals such as nickel,cobalt,and manganese is greater than 95％.
