Advanced and safe lithium-ion battery was important for their electric vehicles(EV) and hybrid electric vehicles(HEV) applications.Herein a novel structured anatase TiO2 nanobundles(PTNBs) with porous structure was prepared through green and convenient hydrothermal strategy starting from the industrial TiO2 powders,it successfully avoided using the expensive organic titanium compounds and the products of PTNBs can exhibit an extremely high capacity of 280 mAh g-1 at 100 mA g-1 and it can further retains the capacity over 146 mAh g-1 even after 500 cycles at 1000 mA g-1(～6 C).
