Commonly, the first stage of the battery recycling process involves shredding to liberate the materials for further processing. In cells where blended electrodes are a common occurrence, or cross-contamination occurs from the shredding of different cell chemistries, direct recycling – where the framework of the material remains intact – becomes increasing more challenging. Here we report a potential strategy for dealing with such complex mixtures, highlighting a selective leaching approach that can allow the selective separation of a commercial Na-ion cathode material (NFM: NaNi1/3Fe1/3Mn1/3O2) from a mixture with a commercial Ni rich NMC (83% Ni) (NMC: LiNi0.83Mn0.06Co0.11O2) cathode material. A simple ascorbic acid treatment selectively dissolves the NFM leaving the NMC as a solid (attributed to the higher Mn content of the former), allowing the subsequent direct recycling/regeneration of the NMC, along with the short loop recycling/regeneration of the NFM. The directly recycled NMC is of high quality, preserving the morphology of the pristine material and illustrating performances matching it. The NFM sample was also successfully regenerated from the leachate via a short loop approach, although further optimisation is required here to match the performance of the pristine NFM. 2026-07-13 published University of Birmingham https://doi.org/10.25500/edata.bham.00001699 Dataset research-data@contacts.bham.ac.uk School of Chemistry yes yes yes TRUE 2024-02-05 2026-06-30
