In the paper, the γ-Mo 2N electrode prepared by dip-calcination method has been characterized by using XRD,SEM and the cyclic voltammetry. The results show that the key to prepare the γ-Mo 2N electrode by dip-calcination method is to select the super-heating rate, the calcination temperature and time,and the reaction system cooling method. The dipping dryness temperature effects noteworthily the adhesiveness with substance and the uniformity of film formed on the electrode. The electrode prepared by the optimum technical condition exhibits the characteristic of capacitor, the reversibility of the kinetics and the remarkable stability and reproducibility of the discharge/recharge behavior.
