Interconnected silicon nanoparticles originated from halloysite nanotubes through the magnesiothermic reduction: A high-performance anode material for lithium-ion batteries

Nanoscale Si can be synthesized in large quantities, originating from halloysite nanotubes, through the magnesiothermic reduction. The obtained nanoscale Si exhibits a high specific capacitance of 3752.4 mA h g−1 at first cycle at 1 A g−1 and 1469.0 mA h g−1 after 400th cycles at current density of 3.5 A g−1, and excellent rate capability of 735.1 mA h g−1 at 5 A g−1 after 1000th cycle and 1050 mA h g−1 at 10 A g−1.289
