A class of improved solid-state electrolytes and methods for forming such electrolytes are discussed herein. The improved electrolytes may be a sodium oxy-sulfide, such as with a nominal composition of Na.sub.3PS.sub.4 _xOx (0<x2). The electrolytes can be synthesized from using a simple one-step ball-milling method. The ball-milling may be performed at high rotation speeds. The resulting ball-milled materials may further be optionally pressed. The pressing may be performed at low or room temperatures and/or relatively low pressure, and the resulting electrolytes achieve high relative densities. The solid-state electrolyte forms a highly dense layer that approaches a continuous glass that is nearly flawless, is mainly amorphous, and/or maintains a stable low-resistance interface with Na metal and Na-alloy electrodes.

Provided is a manufacturing method for a thin phosphor glass plate by which a thin phosphor glass plate can be more certainly produced. A manufacturing method includes the steps of: preparing a phosphor glass base material 21 having a first principal surface 21a and a second principal surface 21b opposed to each other; placing the phosphor glass base material 21 on a stage 22 and fixing the second principal surface 21b onto the stage 22; and polishing the first principal surface 21a of the phosphor glass base material 21 with a polishing member 23 including an abrasive layer 24.

A solid-state electrolyte is provided. The solid-state electrolyte includes an integrated molecular network that results from a mixture including a glass former including sulfur, a glass modifier including sulfur, and a glass co-modifier including lithium oxide or sodium oxide.
