Taiwan’s 1st enclosed crushing and processing line for lithium-ion batteries is engineered to mitigate the emission of particulate matter and electrolyte solvents generated during mechanical comminution. The integrated system comprises sequential units including crushing, magnetic separation, particle sieving, and gravity-based density separation. This facilitates the recovery of high-purity black mass, stainless steel fragments, copper granules, and aluminum granules. The system exhibits the following technical features:

• A proprietary inert gas protection and regulation system significantly enhances operational safety by suppressing thermal and chemical reactivity during battery crushing operation.

• The fully enclosed air capture and solvent condensation system enables the effective recovery of volatilized electrolyte. The recovered solvents, after purification, are suitable for reintegration into lithium-ion battery manufacturing processes, contributing to substantial reductions in product carbon footprint.

• The implementation of a multi-stage magnetic separation module ensures that iron content in the recovered black mass is maintained below 1 ppm, thereby enhancing the efficiency and selectivity of downstream hydrometallurgical recovery processes and improving the quality of extracted metals.

• Gravity separation enables the efficient differentiation of copper and aluminum granules, achieving copper recovery rate of up to 97% and aluminum recovery rate of approximately 86% 

• The total material recovery efficiency of the line exceeds 95%, with recovered products demonstrating high purity and market value, thereby significantly improving the overall economic feasibility of lithium-ion battery recycling operations.
