What is lithium battery? It refers to a secondary battery composed of two compounds that can reversibly intercalate and deintercalate lithium ions as positive and negative electrodes, commonly known as "lithium battery". The structure of lithium battery mainly includes: negative electrode, positive electrode, electrolyte and other auxiliary materials. Copper foil acts as a carrier for negative active materials in lithium batteries. It also acts as the collector and transporter of negative electron flow, so the production process and electrochemical performance of lithium batteries such as tensile strength, compactness, surface roughness, elongation, thickness uniformity and appearance quality of electrolytic copper foil are very large. Key role.

Under the huge consumption of lithium batteries, the consumption of metal resources is quite large. If there is a practical method to recover metals with high economic value and large content in lithium-ion batteries, not only certain economic benefits can be obtained, but also resources. The use of lithium batteries has become the mainstream, and a large number of scrapped lithium batteries have become an environmental pollution problem that we have to face. The purpose of recycling lithium batteries is mainly to recover useful constituent metals. It can not only obtain certain economic benefits, but also resources and realize the hope of sustainable human development. After the lithium battery is crushed, metal elements such as cobalt, copper and lithium in the battery can be recovered, and the pollution problem of waste lithium batteries can be solved, and the economical recycling of resources can be realized.

The recycling of used lithium batteries has both environmental benefits and economic benefits. The valuable metals contained in the positive electrode materials of different power lithium batteries are different, and the metals with the highest potential value include cobalt, lithium, nickel, etc. In the future, as the demand for ternary batteries with high energy density continues to increase, the demand for raw materials such as cobalt and lithium will be even tighter. Therefore, by recycling waste lithium batteries and extracting valuable metals such as nickel, cobalt, and lithium for recycling, it is an effective way to avoid the risks of scarcity of upstream raw materials and price fluctuations, and the economic benefits are significant.
