Silicon Derived from Glass Bottles as Anode Materials for Lithium Ion Full Cell Batteries.

ABSTRACT: 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 pre-leaching 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 ~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.
