In this paper, lithium titanate is prepared by coaxial electrospinning. With the High molecular weight polymer polyvinylpyrrolidone (PVP) providing high viscosity，a solution spinning solution of PVP and absolute ethanol is used as the inner layer template solution. The Part of solution with a lithium source and a titanium source set as an outer layer precursor solution. After the titanate precursor fiber filaments are calcined, with core and outer PVP are removed the hollow lithium titanate filament is finally obtained. Figure a is cycle-capacity curve of the hollow lithium titanate anode material after prepared into a button cell. The first 0.2C rate of the specific capacity is 174.9mAhg-1 with theoretical specific capacity flat, and at the 30C specific capacity can be to 105 mAhg-1, which can achieve that Li-ion battery immediately charge. Figure b shows that, at low charge and discharge rate, lithium titanate discharge platform is relatively stable, while platform stability is poor at the high charge and discharge rate.
