New efficient Recycling Process for Li-ion Batteries

Lithium-ion batteries represent a key technology for the energy transition and electro mobility. Due to the growing battery market the amount of end-of-life batteries increases and thus a valuable source of raw materials. With a new functional and material specific recycling process, the battery materials shall be recovered, reconditioned and reused most efficient. At present energy-intensive metallurgical methods are used to recycle end-of-life batteries and production waste from battery manufacturing or automotive. With these methods only specific elements can be recovered. The added value depends on the market prices of the raw elements copper, aluminum, nickel or cobalt. The aspired recovery of the primal battery materials like Li-, Ni- and Co-containing chemical compounds and high-grade carbons for remanufacturing new cells, is more valuable instead of resynthesizing with high effort. The presented process of electrohydraulic fragmentation is energy- and resource-efficient and suitable for production residues as well as waste products.     «
