The mainstream recovery process of litium batteries is to recover lithium carbonate 、iron phosphate and the ternary precursor cathode material through a hydrometallurgical process (hydrochloric acid leaching-hydrogen peroxide oxidation-soda ash adjustment of pH) When utilizing this dataset for Life Cycle Assessment, users should ensure that the scope of their assessment includes the full recycling process outlined: hydrochloric acid leaching, hydrogen peroxide oxidation, and soda ash pH adjustment. It is recommended to account for the environmental impacts of reagents and energy used in these processing steps. Inclusion of the recovery rates of materials and potential environmental releases during the process should also be considered. The functional unit is '1 tonne of retired lithium iron phosphate batteries and similar waste,' and any comparisons or extrapolations should adhere to this baseline.
