Abstract
Various embodiments provide glass bottle-based silicon electrode materials. A battery electrode includes silicon made from magnesiothermic reduction of silicon oxide derived from glass bottles and a conformal carbon coating thereon. A method of making the electrode material includes crushing glass bottles to produce crushed glass containing silicon oxide particles, mixing the silicon oxide particles with a heat scavenger to produce a mixture, magnesiothermically reducing the mixture to produce silicon, and applying a carbon coat to the silicon to produce an electrode material.
