Abstract
Glass-fiber composites are described that include a substrate containing glass fibers and particles in contact with the glass fiber substrate. The particles may include an alkali-metal containing compound. In addition, batteries are described with an anode, a cathode, and an electrolyte. The cathode may include alkali-metal containing nanoparticles in contact with glass fibers. Also describe are methods of making a glass-fiber composite. The methods may include the steps of forming a wet laid non-woven glass fiber substrate, and contacting alkali-metal containing particles on the substrate.
