Abstract：
 The belongs to electrochemical material preparation field, especially relates to a LiFePO4/Li-Ti-O millimicron fiber compound material with high lithium ion conducting ability. Use strong base hydrothermal method to change TiO2 into millimicron fiber A with fiber-typed micro structure, which is miced with water solution containing Li+, Fe2+ and PO43+ and organic substance, dried, thinning and placed into furnace to be preprocessed, then is burnt to be millimicron fiber compound material with electrochemical performance. The technique need short time for reaction, low temperature for synthesis (n) and fess energy, its particle diameter is adjustable, with average structure and better touching surface, conducting ability and migration ability of lithium ion, which release the step of LiFePO4 in the electrochemical course and realize the application of material in larger speed of charge and discharge.
