[0002] With the rapid development of the new energy vehicle industry, the market share of power batteries has seen a sharp increase. This trend is not only evident in the domestic market, but also globally, as new energy vehicle sales continue to climb, driving enormous demand for power batteries. However, power batteries have a limited service life, typically around five years. Therefore, with the early promotion and application of new energy vehicles, a large number of power batteries are gradually entering retirement.

[0003] Waste power batteries contain rich metal resources and have high recycling value. However, if improperly handled, the electrolyte and combustible materials within them can cause fires and explosions during the shredding process, posing a significant threat to the safety and property of nearby residents and employees.
