Silicon is considered an exceptionally promising alternative to the most commonly used material, graphite, as an anode for next-generation lithium-ion batteries, as it has high energy density owing to its high theoretical capacity and abundant storage. Here, microsized walnut-like porous silicon/reduced graphene oxide (P-Si/rGO) core–shell composites are successfully prepared via in situ reduction...
A novel one-pot chemical dealloying method has been developed to prepare nanocomposite of reduced graphene oxide (RGO) and silicon dendrite from cheap commercial Al–Si eutectic precursor. The RGO anchoring could act as both conductive agent and buffer layer for Si volume change in the application of lithium ion batteries (LIBs). The Si/RGO composites show an initial reversible capacity of 2280 mAh g...
