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 BaFe12O19 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.
