Pyrometallurgy, hydrometallurgy, and direct recycling are three conventional recycling methods . Among them, pyrometallurgy is likely to be of lower relevance for the recycling of Li3InCl6 due to potential cross-reactions with the electrode material in the molten state, leading to the formation of oxychlorides . Hydrometallurgy involving acids and bases may not be applicable in this context, as the use of strong acids (e.g., hydrochloric acid (HCl), sulfuric acid (H2SO4), and nitric acid (HNO3)) is not required to dissolve the SSE, thereby preventing undesired leaching of electrode materials. Consequently, a direct recycling method, specifically a dissolution-based separation method, could be viable if the SSE can be dissolved in H2O and recrystallized while leaving the undissolved electrode materials unaffected.
