MnO(下标 x)基电化学电容器的研究进展

Electrochemical capacitors are charge storage devices between conventional capacitors and recharge able batteries emerging in recent years, which have the characterization of high power and energy density, excellent reversibility and a long cycle life. Recently .manganese oxides have become the subjects of increasing research interest doe to their characterization of extensive resources, low costs, wide electrochemical window, better electrochemical performance, and the fact that manganese oxides are more environmental friendly than any other transition metal oxide systems. This paper introduces the research progress in electrochemical capacitors of manganese oxides based materials at home and abroad, including the synthesis, modification and electrochemical performance.
