Common battery recycling methods include secondary use, disassembly and recycling, recycling, landfill, and incineration.

Secondary use: This method primarily involves screening and repairing discarded batteries, allowing them to continue to function in areas such as energy storage and electric tricycles. This not only maximizes the residual value of the batteries but also reduces the demand for new batteries. However, it is important to note that batteries must undergo rigorous screening and repair before secondary use.

Disassembly and recycling: Disassembly and recycling separate valuable materials such as nickel, cobalt, and lithium from batteries, achieving resource recycling. However, the disassembly process is relatively complex and requires specialized technology and equipment.

Recycling: Recycling involves chemically extracting elements such as lithium, cobalt, and nickel for use in the manufacture of new battery materials. This method reduces costs, but requires chemical processing and may cause some environmental pollution.

Landfill: Landfill is a more traditional disposal method, but it requires careful selection of appropriate sites and methods to prevent battery damage and leakage, thereby contaminating soil and groundwater. Therefore, landfill disposal should be used as a supplement to other disposal methods and conducted under strict supervision.

Incineration: Incineration can reduce the volume of used batteries and destroy hazardous substances. However, the incineration process produces large amounts of smoke and harmful gases, which pollute the atmosphere. Therefore, incineration should be conducted away from human habitation and equipped with high-quality smoke and dust treatment equipment.
