To develop a circular concept for ASSBs that emphasizes full recyclability and reusability, the halide-based solid electrolyte Li3InCl6 presents a promising option. Recent research by Li et al. highlights a water-mediated, one-pot synthesis method for Li3InCl6. This method involves dissolving anhydrous LiCl and InCl3 in deionized H2O, followed by evaporation and subsequent thermal treatment at 200 °C under vacuum. Remarkably, this process allows crystalline and stoichiometric Li3InCl6 to be regenerated after redissolution in H2O and subsequent water evaporation. After an additional crystallization step, the material's initial ionic conductivity (~ 2.05 x 10 -3 S cm -1 ) is recovered 8 . This structural reversibility, without significant electrochemical performance deterioration motivates the exploration of its recycling potential.
