“…However, despite the excellent performance of Si‐C anodes demonstrated in the literature, wide deployment of Si‐C materials in commercial Li‐ion batteries is still illusive. A key challenge for commercialization of Si‐C anode materials is the scalability and cost of the production process: most of the reported high‐performance Si‐C composites require sophisticated synthesis and/or high‐cost precursors as listed in Table S1. Furthermore, demonstration of high performance of Si‐C anodes under realistic conditions such as high areal loading (ie, high areal capacity) is still scarce in the current literature .…”

We report the synthesis of a high‐performance graphitic carbon‐coated silicon (Si@GC) composite material for lithium‐ion batteries via a scalable production route. Porous Si is produced from the magnesiothermic reduction of commercial silica (SiO2) precursor followed by low‐temperature graphitic carbon coating using glucose as the precursor. The obtained Si@GC composite achieves an excellent reversible specific capacity of 1195 mAh g−1 and outstanding cycle stability. The thick Si@GC anode (3.4 mg cm−2) in full cells with commercial lithium iron phosphate cathode delivers a remarkable performance of 800 mAh g−1 specific capacity and 2.7 mAh cm−2 areal capacity as well as 93.6% capacity retention after 200 cycles.
