Abstract

The present invention relates to a polycrystalline solid electrolyte material of the formula (I) M_3-z(Me^k+)_fX_3-z+k*f having at least one of its dimensions that is lower or equal to 100 µm, and having at least another dimension that is greater than or equal to 1 mm. The invention further concerns an electrolyte tape comprising said polycrystalline solid electrolyte material. Finally, the invention pertains to their preparation process comprising the steps of: disposing a compound of formula (I) or an ammonium complex thereof on a substantially planar surface, heating the compound of formula (I) or the ammonium complex thereof at a temperature ranging from 290 °C to 550 °C, and concomitantly or sequentially to the heating step, applying to the compound of formula (I) a pressure that is orthogonal to the substantially planar surface, said pressure ranging from 1.5 MPa to 30 MPa.
