Abstract

A sulfide solid electrolyte manufacturing system comprising: a mixing device that mixes a sulfide solid electrolyte starting material–containing material, a solvent, and a complexing agent to obtain an electrolyte precursor–containing material; a drying device that dries the electrolyte precursor–containing material to obtain an electrolyte precursor; a decomplexing device that removes the complexing agent from the electrolyte precursor to obtain a sulfide solid electrolyte; a separation device that separates the solvent and the complexing agent from at least one fluid which is selected from among a fluid (I) that is supplied from the drying device and contains at least one selected from among the solvent and the complexing agent and a fluid (II) that is supplied from the decomplexing device and contains at least one selected from among the solvent and the complexing agent; and a supply line (1) that supplies the solvent and the complexing agent separated by the separation device to the mixing device.
