The recycling and disposal of wall-mounted energy storage batteries is a crucial part of the entire industry chain, involving safety, environmental protection, and resource reuse. As wall-mounted energy storage batteries (mainly lithium-iron-phosphate batteries) reach the end of their service life (usually 8-10 years), their improper disposal will not only cause environmental pollution but also waste valuable metal resources. Therefore, standardized recycling and disposal processes, adhering to the principles of safety, compliance, and closed-loop management, are essential to realize the sustainable development of the energy storage industry.

The recycling process follows strict standardized procedures, starting with pre-recycling preparation. Professional recyclers must hold a "Hazardous Waste Business License" and sign a recycling contract with the user to clarify transportation and disposal responsibilities. Operators need to have electrician certificates and hazardous waste disposal training certificates, and be equipped with safety protection equipment such as insulating gloves, goggles, and acid-proof clothing, as well as emergency supplies such as baking soda solution and dry powder fire extinguishers. Before dismantling, the energy storage system is switched to bypass power supply, the battery pack is disconnected and fully discharged to avoid short circuits or fires—lithium batteries are discharged to a monomer voltage of ≤2.5V through the BMS, and forced short-circuit discharge is prohibited.

After discharge, the battery pack is physically dismantled in a standardized manner: first, the negative connection line is removed, then the positive connection line, and the wire ends are wrapped with insulating tape immediately. The batteries are sorted and stored separately—damaged or leaking batteries are isolated independently, and lithium batteries and lead-acid batteries are not mixed. The recycled batteries are then transported to professional disposal facilities by qualified dangerous goods transport vehicles, where valuable metals such as lithium, iron, and phosphorus are extracted through harmless treatment, and the electrolyte is recycled to avoid environmental pollution. A complete recycling ledger is established throughout the process, with records kept for at least 3 years to ensure traceability, complying with the requirements of the "Solid Waste Pollution Prevention and Control Law".
