Every year many tons of waste glass end up in landfills without proper recycling, which aggravates the burden of waste disposal in landfill. The conversion from un-recycled glass to favorable materials is of great significance for sustainable strategies. Recently, silicon has been an exceptional anode material towards large-scale energy storage applications, due to its extraordinary lithiation capacity of 3579 mAh g(-1) at ambient temperature. Compared with other quartz sources obtained from preleaching processes which apply toxic acids and high energy-consuming annealing, an interconnected silicon network is directly derived from glass bottles via magnesiothermic reduction. Carbon-coated glass derived-silicon (gSi@ C) electrodes demonstrate excellent electrochemical performance with a capacity of similar to 1420 mAh g(-1) at C/2 after 400 cycles. Full cells consisting of gSi@ C anodes and LiCoO2 cathodes are assembled and achieve good initial cycling stability with high energy density.
