When the last electric vehicle is retired, its power battery doesn't reach the end of its life, but is sent to a 120-meter-long battery crushing, separation, and recycling production line. Here, four core processes—electric crushing, low-temperature evaporation, intelligent sorting, and efficient leaching—are connected to form a "green closed loop": 1. Electric crushing: No discharging is required. The battery is directly shredded, preventing electrolyte leakage. Dust and VOCs are collected simultaneously, with a purification rate of 99%. 2. Low-temperature evaporation: Precise temperature control at 300°C allows electrolyte and plastic films to be removed first, while copper and aluminum foils are preserved intact, reducing energy consumption by 30%. 3. Intelligent sorting: AI vision and multi-sensor fusion enable one-time identification of copper, aluminum, and black powder, with a purity of 98% and a metal recovery rate of 95%. 4. Efficient leaching: Gradient acid leaching in a sealed reactor recovers 98% of lithium, nickel, and cobalt, with 100% reuse of residual acid and zero wastewater discharge. The entire line only requires six operators, and can process 2 tons of batteries per shift, equivalent to "reviving" the batteries of 1.2 million mobile phones. The recycled materials are reintroduced into battery factories, truly achieving an infinite cycle of "battery-to-battery". Choosing this production line means choosing to leave pollution in the past and entrust resources to the future.
