Preparation of BaFe₁₂O₁₉ as anode material for lithium-ion batteries through sol-gel method

The BaFe₁₂O₁₉ nanocrystalline was prepared via a sol-gel process. The structure, morphology and electrochemical properties of the nanocrystallines were detected by means of XRD, TEM, TGA and electrochemical measurements. This BaFe₁₂O₁₉ is firstly used as anode electrode material for lithium-ion batteries. The mechanism of BaFe ₁₂O₁₉ with Li will also be discussed. The reversible specific capacity of BaFe₁₂O₁₉ is 959.5 mAh/g. A capacity of 358.3 mAh/g can be retained after 50 cycles which will have a broad space for improvement with modifying.
