Cost-effective direct regeneration of spent NCM cathode via solvothermal regeneration process

Key Points

• This study aims to explore a more cost-effective method for regenerating spent NCM cathodes from lithium-ion batteries using a solvothermal process.
• Utilized a solvothermal regeneration process to treat spent NCM cathodes.
• Compared the efficiency and cost-effectiveness with conventional methods.
• Assessed environmental impacts of the new method.
• Successfully regenerated NCM cathodes with over 90% efficiency.
• Achieved cost reductions up to 30% compared to traditional methods.
• Proposed the method as a greener alternative to conventional pyrometallurgical processes.
