However, the use of solvent extraction and precipitation techniques is recommended as strategies for high-efficiency recovery of the elements. The great challenge in lithium-ion battery samples is the separation of aluminum from the other elements; thus, the separation of aluminum is the first step to be carried out.
The separation and purification of lithium battery from NCA chemistry were chosen by the few references found about this specific type of battery, which has potential for growth given the use of lower cobalt content and high availability of aluminum in the global market.
The use of lithium in manufacturing of lithium-ion batteries for hybrid and electric vehicles, along with stringent environmental regulations, have strongly increased the need for its sustainable production and recycling. The required purity of lithium compounds used for the production of battery components is very high (> 99.5%).
It is observed that the hydrometallurgical route for extracting the elements present in lithium-ion batteries requires many steps of purification techniques to recover each element separately. However, the use of solvent extraction and precipitation techniques is recommended as strategies for high-efficiency recovery of the elements.
Despite some methods achieving recovery rates of up to ninety-nine percent, the global recovery rate of lithium from lithium-ion batteries (LIBs) is currently below 1%. This is due to the high energy consumption for lithium extraction and the high operation cost associated with the processes .
In response, a burgeoning industry has emerged dedicated to the recovery of lithium from discarded electronics and batteries. This growth is largely driven by the EV sector, where LIBs are pivotal in powering the green revolution and supporting the global transition to sustainable energy solutions .
