A treated silica depleted rice hull ash product (SDRHA) comprising silicon oxide at ≤about 65% by weight and carbon ≥about 35% by weight may be heated in an environment free of any additional carbon sources, but in an inert atmosphere, having a temperature of ≥about 1,200° C. to ≤about 1,700° C. for a carbothermal reaction that forms a product (e.g., nanocomposite product) comprising at least one of silicon carbide (SiC), silicon nitride (SiN), and silicon oxynitride (SiNO or non-stoichiometric SiNO, where x ranges from greater than 0 to less than 4). A negative electroactive material is also provided that includes silicon oxynitride (SiNO), which may be used in a lithium ion battery.",
