Problems solved by technology

[0003] Existing cell material recycling and sorting equipment, when performing eddy current sorting on crushed cell materials, is likely to be affected by the adhesion of electrode materials and membrane materials due to too much material input into the magnetic field at one time or due to grinding and rolling. The eddy current sorting effect leads to the low quality of the sorted materials and affects the subsequent use, and because the sorted electrical materials are relatively small, part of them is easy to be adsorbed on the surface of the material guide plate, and it is difficult to take out, resulting in a certain loss

Abstract

The invention relates to the technical field of lithium battery recovery, in particular to a waste power lithium battery recovery method, which comprises the following steps: S1, energizing the wastepower lithium battery and releasing the residual electric quantity in the lithium battery; S2, placing the lithium battery treated in S1 into a lithium battery comprehensive treatment equipment for crushing and sorting; S3, sorting and storing different materials selected in S2, and recovering them respectively. The method ensures the safety of the lithium battery recovery by releasing the electric quantity of the lithium battery, and the lithium battery comprehensive treatment equipment designed by the inventor can realize the high-efficiency sorting of the lithium battery, thereby improvingthe efficiency of the lithium battery recovery.

Description

technical field [0001] The invention relates to the technical field of lithium battery recycling, in particular to a method for recycling waste power lithium batteries. Background technique [0002] Lithium-ion power battery is a new type of high-energy battery successfully developed in the 20th century. The negative electrode of this battery is metal lithium, and the positive electrode is MnO2 or SOCL2. It entered practical use in the 1970s because of its high energy, high battery voltage, and wide operating temperature range. , long storage life and other advantages, have been widely used in military and civilian small electrical appliances, lithium-ion power batteries have partially replaced traditional batteries in mobile phones, portable computers, video cameras, cameras, etc., and large-capacity lithium-ion batteries have been used in electric vehicles Trial, will become one of the main power sources of electric vehicles in the 21st century, and has been applied in art...
