The present invention provides an additive containing sulfide-based solid electrolyte having an acidic component attached to the sulfide-based solid electrolyte. The sulfide-based solid electrolyte comprises a —PS structure having at least a phosphorous atom and a sulfur atom. The acidic component carries a positive charge which could firmly attach to the sulfur atom of the —PS structure of the sulfide-based solid electrolyte. The present invention utilizes the acidic component as the additive to enhance the water or vapor resistance ability to the sulfide-based solid electrolyte. By using compatible acidic component, the additive could firmly attach to the sulfur atom of the —PS structure of the sulfide-based solid electrolyte but still maintaining in good electrical properties. By enhancing the sulfur atom of the —PS structure of the sulfide-based solid electrolyte, the present invention could benefit the mass production for such material.
