XRD analyses revealed Bi-layered perovskite structure in all samples.
Introduction Bismuth titanate, Bi4Ti3O12 (BIT), belongs to the family of ferroelectric materials with perovskite layered structures.
La [3], V [5] and Nd [6] have been used to substitute partly Bi, and the Bi-layered perovskite structure is maintained in such a bulk or film.
It is evident that the Bi-layered perovskite structure has been maintained after substitution of Sm for Bi.

Fig. 1f shows a Fourier Transform (FT) of the k2-weighted extended X-ray fine structure.
Firstly, their highly porous structure and large surface area may arise some extra capacity.
Although the exact mechanism is still not clear, it is generally think that the mesporous structures and the nano-hollow structures of the anode material could store some extra Li ion which contributed to the capacity of the electrode materials [8-11]; Secondly, the partially reversible of Eq. 1 accounts for some extra capacity of these samples.
