Improper disposal of waste lithium batteries causes resource waste and environmental pollution. Crushing and sorting recycling uses a safe, enclosed physical process to efficiently separate valuable materials like copper, aluminum, lithium, nickel, and cobalt. Practical advantages: Recovers high-value metals, reducing reliance on natural mineral mining. Eliminates toxic electrolytes and dust, protecting soil and water from contamination. Produces high-purity recycled materials that can be reused in battery manufacturing, improving economic efficiency. This technology provides a reliable, environmentally friendly and resource-efficient solution for the circular new energy economy.
