Recycle cathode materials from spent lithium-ion batteries by an innovative method

Recycle cathode materials from spent lithium-ion batteries by an innovative method The worldwide consumption of lithium ion batteries grows year by year, and the process of recycling batteries is complex and harmful today. To solve this problem, a novel method which is green and simple is proposed. The process for recycling and regeneration from spent lithium ion batteries is acid-free, which is different from conventional chemical leaching and solid-state synthesis approach. The impacts of reaction temperature and time, solution concentration on the regeneration of the cathode materials are investigated systematically. Lots of characterizations, such as XRD, SEM, and ICP, are adopted to investigate the properties of the regenerate NCM523, which conclude it has ideal stoichiometry and phase purity; the electrochemical results certify that the regenerated NCM523 meet the commercial requirements for reuse. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Ionics Springer Journals

Abstract

The worldwide consumption of lithium ion batteries grows year by year, and the process of recycling batteries is complex and harmful today. To solve this problem, a novel method which is green and simple is proposed. The process for recycling and regeneration from spent lithium ion batteries is acid-free, which is different from conventional chemical leaching and solid-state synthesis approach. The impacts of reaction temperature and time, solution concentration on the regeneration of the cathode materials are investigated systematically. Lots of characterizations, such as XRD, SEM, and ICP, are adopted to investigate the properties of the regenerate NCM523, which conclude it has ideal stoichiometry and phase purity; the electrochemical results certify that the regenerated NCM523 meet the commercial requirements for reuse.
