Environmentally friendly recycling and rejuvenation of used lithium-ion battery cathode materials

With more electric cars and the use of LIBs for green energy, the market has to accept a lot of batteries, which are now harming the environment and resources. Although LIBs rely on lithium, cobalt, and nickel to function well, their cathodes may become hazardous when not disposed of correctly. The study examines and evaluates technologies to restore LIB cathode performance for battery use. A range of techniques is discussed in the article by covering their role in improving usefulness, scaling capacity, and their effect on the environment. Producing new regenerative processes is better for the environment, uses resources more efficiently, and requires less energy than traditional pyro and hydrometallurgy. At this time, delivering direct regeneration to the market is difficult, as arranging the different materials and selecting the proper sorting and regeneration processes have proved challenging. Efforts should be made to connect or combine automated, set modules with different diagnostic systems for the large-scale creation of organ replacements. Applying this technology will support the circular economy and allow us to use less raw material in the future.
