This article explores the importance of discharging lithium-ion batteries (LIBs) before recycling to ensure safety and environmental friendliness. The study focuses on the effectiveness of discharging LIBs at different temperatures, particularly at 35 °C, which results in significantly reduced residual energy. The research highlights the advantages of non-electrochemical discharge methods, such as using conductive powder, over electrochemical discharge methods, which can be more complex and environmentally harmful. The study also proposes a self-heating method to enhance the discharge process, reducing the need for external heating equipment. The findings emphasize the importance of optimizing discharge conditions to minimize safety risks and improve the efficiency of LIB recycling processes. The research contributes to the scientific understanding of non-electrochemical discharge methods and provides valuable insights for improving the sustainability of LIB recycling.This article explores the importance of discharging lithium-ion batteries (LIBs) before recycling to ensure safety and environmental friendliness.
