## Description

- description: We systematically explored the formation range of α-NaFeO2 type layered
    titanate, its ion-exchange behaviors, and electrochemical performance. The layered
    sodium titanate of NaxTi1−x/3Lix/3O2 at x = 0.68–0.70 was synthesized by the solid-state
    reaction at 900 °C. The titanate is composed of coplanar host layers with the
    α-NaFeO2 type structure. The interlayer Na+ ions underwent facile exchange with
    other alkali metal ions in the aqueous solutions at 80 °C, accompanied by concurrent
    exchange with proton/oxonium ions. Powder X-ray diffraction data on the products
    and its Rietveld refinement revealed the formation of a unique staging structured
    titanate, in which the interlayer galleries are alternately occupied by incoming
    alkali metal ions and oxonium ions. The electrochemical intercalation/deintercalation
    properties for Li+ and Na+ ion storage were examined on the pristine sodium titanate
    and its ion-exchanged derivatives. The staging structure was found to provide
    superior electrochemical performance, which may be due to the rather open nature
    of the interlayer galleries, providing abundant sites for Li+ and Na+ ions.
