The full life cycle of batteries

The full lifecycle value chain of power batteries refers to "power battery recycling - nickel cobalt lithium battery raw material recycling - battery material recycling - power battery recycling". Taking power batteries as an example, when the existing capacity of power lithium batteries only accounts for 80% of the original capacity, the electrochemical performance of power lithium batteries will be difficult to meet the normal power needs of electric vehicles, and can be recycled and processed. The recycled and processed waste power lithium batteries and their materials can ultimately be reused in the field of lithium batteries or powder metallurgy. Cascade utilization refers to the retirement and testing of batteries on electric vehicles that have decreased their performance to below 80% of their initial performance, and then the selection and recombination of batteries with better performance for secondary utilization in some relatively mild usage conditions. Retired batteries under cascading utilization are mainly used in energy storage, telecommunications base stations, and low-speed electric vehicles.
