Synthesis of micro-assembled Si/titanium silicide nanotube anodes for high-performance lithium-ion batteries

Chemical reduction of micro-assembled CNT@TiO2@SiO2 leads to the formation of titanium silicide-containing Si nanotubular structures. The Si-based nanotube anodes exhibit a high capacity (>1850 mA h g−1) and an excellent cycling performance (capacity retention of >99% after 80 cycles).
