In this work, Na2Ti3O7 is fabricated as lithium storage material via one-step solid state reaction. Worked as anode material, Na2Ti3O7 delivers a stable electrochemical performance with good lithium storage capability. Structural analyses show that Na2Ti3O7 anode experiences slight volume change during electrochemical lithiation/delithiation process. Moreover, the reversibility of structural evolution is further demonstrated by in-situ X-ray diffraction technique. All these evidences prove the cycling stability of Na2Ti3O7 as lithium storage material. Besides, the kinetic properties of the Li+ ion storage in Na2Ti3O7 are systematically investigated. The observed results reveal that Na2Ti3O7 delivers the lithium ions diffusion coefficient in the range of 10−14–10−12 cm2 s−1 during the discharge process and 10−15–10−12 cm2 s−1 during the recharge process. It suggests that Na2Ti3O7 has good lithiation/delithiation kinetics in rechargeable batteries.
