英文摘要：

Ordered porous titanium phosphate materials were prepared by using the surfactant template combined with the sol-gel method. The samples were characterized by small angle X-ray diffraction（SA-XRD） method, N2 adsorption/desorption techniques, high resolution transmission electron microscopy （HRTEM） and element analysis. It is found that the calcination temperature is a big influence on the porous structure, and electrochemical performance of the titanium phosphate materials. , and the mesoporous titanium phosphate showed good performance in the electrochemical test , the first discharge capacity is 94 mAh/g at the current density of 150 mA/g. On the other hand, the no porous material with a low capacity of 37 mAh/g under the same charge-discharge condition.
