Introduction	Every year, substantial quantities of waste glass are sent to landfill sites without adequate recycling, exacerbating challenges associated with landfill disposal. Converting non-recycled glass into valuable materials is essential for sustainable practices. Silicon has recently been regarded as a noteworthy anode material for large-scale energy storage applications, due to its impressive lithiation capacity of 3579 mAh g−1 at ambient temperature. Unlike other quartz sources that require hazardous acids and energy-intensive annealing processes, a silicon network is obtained directly from glass bottles through magnesiothermic reduction. Carbon-coated glass-derived silicon electrodes display strong electrochemical performance, maintaining a capacity of approximately 1420 mAh g−1 at C/2 over 400 cycles. Full cells using these anodes and LiCoO2 cathodes indicate promising initial cycling stability and high energy density.
