Preparation and Chracteristion of Graphite Doped Tin Oxide Anode Material for Lithium-Ion Battery

A citric acid assisted sol gel method has been used to prepare a composite of tin oxide doped with 10% and 20% graphite. The structure, morphology and the electrochemical properties of the composite powders were investigated. The x-ray diffraction(XRD) pattern showed crystalline tetragonal structure...
