Disclosed is a process for the production of lithium ion conductive shaped particles, or precursors thereof, comprising: feeding a mixture of raw materials into a melting vessel, melting the raw materials in the melting vessel to form a molten mass, shaping the molten mass, and quenching the molten mass to produce the particles, wherein the cooling rate of the molten mass is sufficient to form a plurality of glass or glass ceramic particles and wherein the molten mass is shaped prior to or at the same time as being quenched by a fluid cooling medium.
A process for the production of a lithium ion conductive shaped articles, or a shaped article capable of transformation thereto, comprising:
