Core Insights - A new efficient and environmentally friendly lithium-ion battery recycling method has been developed by a research team at Worcester Polytechnic Institute, published in the latest issue of "Energy Storage Materials" [1] Group 1: Recycling Technology - The traditional recycling methods for used lithium-ion batteries have low efficiency in processing nickel-poor cathode mixed materials and rely on high-energy consumption processes, resulting in limited material value [1] - The new technology can recover over 92% of key metals such as nickel, cobalt, and manganese, and convert them into high-performance cathode powder [1] Group 2: Performance of Recycled Materials - Batteries made from this recycled material demonstrate excellent performance, maintaining 88% capacity after 500 charge-discharge cycles and over 85% capacity retention after 900 cycles in commercial pouch battery tests [1]
