The dissolution of Co ions from NCA is visually apparent, evidenced by a blue discoloration at the bottom of the flask upon evaporation (see Figure ). This discoloration can be attributed to the transferred cobalt species. Thus, the ICP-MS analysis of pristine, redissolved, and recycled Li3InCl6 after separation from different electrode materials highlights significant compositional changes and different Li-In-Cl ratios, with the dissolution of Li and TM ions from different electrode materials partially acting as dopants in the recycled electrolyte.
