Abstract

The invention pertains to a recycling process of a material comprising a halide solid electrolyte (HSE) of formula (I) M_3-z(Me^k+)_fX_3-z+k*f, said process comprising successively: a) adding (an) ammonium salt(s) of X' to a solution comprising the HSE, wherein X and X' are halogens, in particular independently chosen from Cl, Br, I and any combination thereof; b) filtering and evaporating the solution obtained in step a) to obtain a dry powder; c) heating the dry powder obtained in step b), and d) obtaining a recycled HSE of formula (I). The invention further concerns a cathode composite and an electrolyte comprising a recycled HSE obtained from the recycling process according to the invention and an all-solid-state battery comprising such a cathode composite and/or electrolyte.
