Universal and efficient extraction of lithium for lithium-ion | ResearchBunny

Abstract

This paper reports a highly efficient, acid-free mechanochemical process for recycling lithium from various cathode materials (LiCoO₂, LiMn₂O₄, Li(CoNiMn)O₂, LiFePO₄) using aluminum as a reducing agent. Two processes were developed to recover lithium as pure Li₂CO₃, achieving recovery rates up to 70% without corrosive leachates or high temperatures. The process shows promise as a universal and sustainable method for lithium-ion battery recycling.
