摘要
超级电容器是一种具有高的功率密度、良好的循环稳定性和快的充放电速率的储能器件。与传统的电容器相比,由于受到较高的成本和较低能量密度的限制,超级电容器目前仍很难替代传统能源。在此前提条件下,寻求一种电化学储能能力更强、成本更低的电极材料是目前超级电容器电极材料的研究重点。二氧化锰由于其价格低廉、来源广泛和能量密度高的优点成为当前研究最为广泛的电极材料之一。该文以二氧化锰基的纳米复合材料为研究对象,从二氧化锰的制备与改性方法的角度出发,总结了当前二氧化锰基的纳米复合材料在超级电容器方面的应用研究进展,并对未来的发展趋势提出了展望。
Supercapacitor is a kind of energy storage device with high power density,good cycle stability and fast charge and discharge rate.Compared with traditional capacitors,supercapacitors are still difficult to replace traditional energy due to their higher cost and low energy density.In this context,it is focused on developing low-cost and excellent electrochemical performance electrode for supercapacitor.Manganese dioxide(MnO_(2))has become one of the most widely studied electrode materials because of abounding source and high energy density.In this paper,we have summarized the preparation and modification methods of MnO_(2)based nanocomposite materials for supercapacitor.Finally,we have also proposed the research trend of MnO_(2)-based nanocomposite materials for supercapacitor in the future.
