Hybrid electrochemical capacitors composed with molybdenum trioxide as negative materials and activated carbon as positive materials were studied in 1 mol/L NaPF₆-propylene carbonate(PC). The voltage window of the electrochemical capacitors is in the range of 0~3 V,the energy density and power density is 33.0 W·h/kg and 595.6 W/kg respectively,the capacity is reduced to 93.8% after 1000 cycles compared with the 20th cycle,and the coulombic efficiency reaches 95.1% of the value of the 20th cycle.
