Analysis of power battery recycling channels

　　After the power battery is retired from the car, its charging and discharging performance cannot meet the power demand of the vehicle, but the internal chemical composition of the battery has not changed. It can be used in places with lower requirements than the car’s electrical energy, and used in energy storage or related power supply. Base stations, street lights, low-speed electric car bodies, etc., are eliminated and finally enter the recycling system. In summary, it is divided into two cyclic processes:

　　①Echelon use:

　　The battery capacity is reduced, making the battery unable to make the electric vehicle run normally, and it can still be used in other ways, such as electricity storage. (Note: the battery itself has not been scrapped)

　　②Dismantling and recycling:

　　The battery cannot be used continuously because the battery capacity is severely depleted. The only way to recycle the battery is to recycle valuable renewable resources.

　　The Chinese government has clearly adopted the extended producer responsibility system, as shown in Figure (1). But the implementation of this system has not yet started. Recycling channels have not yet been established. This is a key issue that needs to be resolved urgently.
