The process involves acid treatment (delithiation, step 2) of LIS (LMO/LTO) to regenerate LIS (HMO/HTO), followed by Li recovery (lithiation, step 4) from Li-bearing solution using the generated LIS (HMO/HTO). The diagram also illustrates the regeneration of the LIS material (LMO/LTO) for subsequent cycles.
