Abstract	Hydrogen titanate (H2Ti3O7) anode materials with desirable electrochemical performance, such as long cycling life and high capacity, have rarely been reported so far. In the present work, as-prepared hydrogen titanate with a particularly hierarchical nanostructure exhibits a breakthrough in electrochemical performance as an anode material for lithium-ion batteries by morphology engineering and heat treatment: 168 mA h g−1 at 16.8 A g−1, meaning that a full charge only needs 40 seconds; 184.8, 176.4 and 156.8 mA h g−1 at 0.168, 1.68 and 10.08 A g−1 after 1000 cycles, respectively; 120 mA h g−1 at 10.08 A g−1 even after 4000 cycles. It is believed that such excellent performance makes hydrogen titanate a promising anode material for advanced lithium-ion batteries with ultra-long life and high power density.
