[0002] With the rapid development of China's new energy vehicle industry and electronic products, the usage of lithium batteries has increased year by year. However, if waste lithium batteries are not properly disposed of, they will cause serious environmental pollution and ecological damage. At the same time, lithium batteries contain many valuable metals and compounds, such as rare metals like lithium, nickel, cobalt, as well as rare earths and other compounds with relatively high value. These materials can achieve the maximum utilization of resources through recycling. Therefore, whether from the perspective of environmental protection or from the perspective of recycling resources to reduce production costs, the recycling and reuse of waste lithium batteries are very important. However, the recycled waste lithium batteries may catch fire in the storage place due to internal faults, external damages, material aging, or environmental factors.
