In this study an attempt has been made to review the use of anode material for Li ion batteries, with a special focus on Cobalt Ferrite. The review includes a discussion of historical background, review of Cobalt Ferrite and some yesteryear anode materials.

A novel Barium Titanate-Zinc ferrite (BaxTiO3-ZnXFe2O4) heterostructure nanocomposites are synthesized at temperatures less than 500ºC which is the major theme of the present research. The synthesis technique is adapted in such a way that the size of the particle is governable. In this research two dissimilar ratios of BTO (hard-site) and ZFO (soft-site) composites are synthesized (H-S 90:10, H-S 60:40) and quantitatively analyzed for their exclusive structural, textural, spectroscopic, and optical properties. With XRD data, structural refinement has been carried out showing 49 % of harder-BTO phase (Triclinic) and 51% of softer-ZFO phase (Cubic) for H-S 90:10 and similarly 78% of harder-BTO phase and 22% of softer-ZFO phase in the H-S 60:40 composite respectively. Very small particles of 6nm are found which is confirmed by SEM histogram and sample purity was determined using EDX analysis. Proofs for the formation of nanocomposites and the existence of Tetrahedral and Octahedral phases for each sample were given using FTIR Spectroscopy. From UV spectrometer data, Tauc’s plot is used to find the wide energy band gap which is observed to be 2.6651 and 3.1971 eV, thus proving that these composites can present themselves as a budding candidate for nano-level optoelectronic devices and other photovoltaic applications.
