Natural halloysite was used as precursor and template to prepare silicon nanotubes through low temperature aluminothermic reduction. The mechanism of variation in morphology during the reduction process and the lithium storage performance of the silicon nanotube were studied. It was found that the alumina octahedron in the natural halloysite was helpful to maintain the one-dimensional nanotube structure of the products during the low temperature aluminothermic reduction process, leading to the formation of silicon nanotubes. The silicon nanotubes had excellent electrochemical performance when used as anode of lithium-ion batteries, with an initial specific capacity of 3 150 mA·h/g. After 50 cycles, the specific capacity was still 1 977 mA·h/g, which is more than twice the value of commercial silicon anode. At a current density of 2 A/g, the capacity was maintained to be 913 mA·h/g after 200 cycles, which is also much higher than that of commercial silicon anode.
