Adding chemicals to the process can reduce the amount of energy required but often leads to the production of a hazardous by-product.Researchers at the Karlsruhe Institute of Technology (KIT) in Germany have developed an inexpensive and environmentally friendly method for recycling lithium from batteries.

A collaboration between the researchers at KIT’s Energy Storage Systems Department and Helmholtz Institute Ulm for Electrochemical Energy Storage (HIU) in Germany used a mechanochemical approach for the recovery of lithium.mechanical processes are used to bring about chemical reactions that give much higher yields of desired products while consuming lesser energy and improving sustainability.Herein we report a highly efficient mechanochemically induced acid-free process for recycling Li from cathode materials of different chemistries such as LiCoO2.

all used recycling technologies are always associated with large energy consumption and utilization of corrosive reagents.Two different processes have been developed to regenerate lithium and transform it into pure Li2CO3.

the method is also scalable and can be deployed at an industrial scale when a large number of batteries become available.

The key innovation is that the regeneration of lithium was successfully performed for all relevant cathode chemistries.many of these images are taken straight down.
