摘要本工作采用液相沉淀法制备了二氧化锰@碳纳米球电极材料,通过碳纳米球复合的方式对二氧化锰进行改性。经XRD分析可知,合成的材料以水钠锰矿的形式存在;由TEM和SEM分析可知,碳纳米球均匀分布在片层状二氧化锰的表面,使其更加饱满充实。由电化学测量可知,适量碳纳米球的引入明显提高了材料的电化学性能,在二氧化锰复合碳纳米球摩尔分数为100%时,所得材料拥有最佳比容量,即在1 A· g^-1电流密度下放电比容量为166.3 F·g^-1,当电流密度增加到10 A·g^-1时,材料的比容量仍能保持在135.9 F·g^-1,经历2 000次循环后电容保持率高达95.1%,说明材料具有优异的倍率特性和较高的稳定性。这可能是由于引入碳纳米球后提高了水钠锰矿的导电性,从而增加了其活性位点的数量。

Abstract: In this paper, manganese dioxide nanosheets@carbon nanospheres electrode material was prepared by liquid phase precipitation method. XRD analysis showed that the synthesized material was in the form of sodium manganese dioxide. Electrochemical measurements showed that the introduction of appropriate amount of carbon nanospheres significantly improved the electrochemical properties of the materials, and the 100 mol% carbon nanospheres composite material had the best specific volume: the specific capacity was 166.3 F · g^-1 at the current density of 1 A · g^-1. When the current density increased to 10 A · g^-1, the specific volume remained at 135.9 F · g^-1, and the capacitance retention rate was 95.1% after 2 000 cycles, which indicated that the material had excellent rate capacity and high stability. Maybe that’s because the elevated conductivity increased active sites number of sodium manganese with the introduction of carbon nanospheres.

Key words: manganese dioxide carbon nanosphere lamellar structure supercapacitor
