Closed Loop Lithium Ion Battery Recycling Process

Recycling spent lithium-ion batteries can play a significant role in alleviating the shortage of raw materials and environmental problems. However, recycled materials are usually deemed inferior to commercial materials in terms of electrochemical performance, preventing the industry from adopting recycled materials in their batteries. Here, we develop a closed loop lithium ion battery recycling process which can recover most of the battery materials and we also demonstrate that the recycled materials have a superior rate and cycle performance, verified by various industry-level tests. The recycled material outperforms commercially available equivalent, providing a green and sustainable solution for spent lithium-ion batteries.
