First, the type of lithium battery plays a significant role. NMC (Nickel Manganese Cobalt) and LFP (Lithium Iron Phosphate) batteries contain different ratios of valuable metals, which influence recovery rates. And you also need to consider the recycling technology in use. Mechanical processes can recover metals like copper and aluminum efficiently, but advanced hydrometallurgical or pyrolysis methods achieve higher recovery of critical elements such as lithium, nickel, and cobalt.
