Na2Ti7O15 nanotubes on a Ti net substrate were fabricated for the first time and used directly as a binder-free anode for Na-ion batteries. This material exhibited high reversible capacity and excellent stability which might be due to its unique characteristics including the porous substrate, nanoscale large surface area, nanotube structure and so on.
