The French Alternative Energies and Atomic Energy Commission has been starting a key program on the development of Li-ion technologies for applications such as green transportation and stationary energy storage. Among them, the technologies based on LFP and LTO active materials are now transferring at industrial scale. In parallel, the recycling has to be considered for production scrap and batteries end of life.In this domain, two main issues arise:- The European regulation fixes at 50% the minimal recycling rate,- The economical balance of current recycling processes is threatened by materials without Co, Ni or Mn.A study has been initiated on the recycling of such materials by hydrometallurgy in order to maximize the value of main elements by reintroducing them in the new active materials synthesis. Lithium and Iron were recovered, separated and turned into phosphates or carbonates with high purity and high recovery rate.
