show that the amounts of these metals in solution are considerably smaller compared to the amount of Mn present. Therefore, the ICP-OES results support the conclusion that it is mainly the LMO component that is leached into solution. Furthermore, the percentage of Al in solution is low suggesting that the leaching process does not result in significant loss of Al from the current collector. This suggests that from this solution, the LMO could be reformed from the solution with only a small amount of Ni/Co/Al contamination.
