Fiber-reinforced separators/solid electrolytes suitable for use in a cell employing an anode comprising an alkali metal are disclosed. Such fiber-reinforced separators/solid electrolytes may be at least partially amorphous and prepared by compacting, at elevated temperatures, powders of an ion-conducting composition appropriate to the anode alkali metal. The separators/solid electrolytes may employ discrete high aspect ratio fibers and fiber mats or plate-like mineral particles to reinforce the separator solid electrolyte. The reinforcing fibers may be inorganic, such as silica-based glass, or organic, such as a thermoplastic. In the case of thermoplastic fiber-reinforced separators/solid electrolytes, any of a wide range of thermoplastic compositions may be selected provided the glass transition temperature of the polymer reinforcement composition is selected to be higher than the glass transition temperature of the amorphous portion of the separator/solid electrolyte.

The present disclosure includes carbon-carbon composite articles having oxidation protection coatings for limiting thermal and catalytic oxidation reactions and methods for applying oxidation protection coatings to carbon-carbon composite articles.
