摘 要：In order to overcome the problem that the low conductivity and high content of graphitic N will lead to serious irreversible capacity loss,magnesiothermic denitriding method was employed to fabricate nitrogen deficient g-C3N4 （ND-g-C3N4）.By controlling the reaction conditions,ND-g-C3N4-675 with optimal electrochemical properties was obtained.The ND-g-C3N4-675 has thinner two-dimensional porous structure,with high specific surface area and good conductivity.The ND-g-C3N4-675 showed superior cyclic stability and rate capability (After 500 cycles under 1 000 mA·g-1,2 264.9 mAh·g-1 was obtained).Moreover,it presented high initial coulombic efficiency （42.2%）.
