摘要
以三氧化钼（MoO3）作为负极材料，活性炭（AC）作为正极材料，组成混合型电化学电容器。研究了电容器在1mol／LNaPF。的碳酸丙烯酯（Pc）中的电化学性能，其电位窗为0～3V，能量密度和功率密度分别达到33．0W·h／kg和595．6W／kg，经1000次循环后容量为第20次的93．8％，库仑效率在经过20次循环后达到95．1％以上。
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 coulombie efficiency reaches 95. 1% of the value of the 20th cycle.
