Description

Technical Field

[0002] With the popularity of electronic products such as electric vehicles and smart phones, the use of lithium batteries has increased rapidly. However, improper handling of waste lithium batteries will not only cause waste of resources, but may also cause environmental pollution. Therefore, the effective treatment and recycling of waste lithium batteries is of great significance. By recycling useful metal materials such as lithium, cobalt, copper, aluminum, etc. in waste lithium batteries, resources can be reused. These materials can be used to manufacture new lithium batteries or other applications; methods for recycling waste lithium batteries include mechanical decomposition, high-temperature pyrolysis, hydrometallurgy, etc. These methods can effectively extract useful metals from waste lithium batteries. For waste lithium batteries that cannot be recycled, environmentally friendly treatment is required. Useful materials in waste lithium batteries can be reused to manufacture new lithium batteries or other applications, such as building materials, ceramic materials, etc. This further improves the utilization rate of resources. The treatment of waste lithium batteries covers multiple aspects such as recycling, environmentally friendly treatment and reuse. With the advancement of technology and the promotion of policies, the recycling rate of waste lithium batteries will continue to increase, contributing to environmental protection and resource reuse.
