| 摘 要： | 锰化合物是有比容量高的超级电容器材料。微纳结构作为一种材料的组成方式,同时具有纳米材料和微米材料的优点。本文通过水热法一步制备了MnCO_3,并在空气中热处理后得到Mn_2O_3。SEM分析结果表明水热法制备的MnCO_3是由纳米级立方组成的微米实心球,Mn_2O_3是由纳米颗粒组成的微米实心球。将MnCO_3和Mn_2O_3与Super P复合,并研究复合物的电化学性能,测试结果表明,复合Super P后MnCO_3与Mn_2O_3的比电容值都得到大幅度提高。当比例为9∶1时,MnCO_3/Super P电容最大可达到207F·g~(-1),远高于Mn_2O_3复合物。

| Abstract: | Manganese compounds are used as high-capacity electrode materials for supercapacitor Micro/nanostructure materials have the advantages of both nano-materials and micro-materials. In this paper,MnCO3were prepared by hydrothermal method,which transferred to Mn2O3after heat treatment at 600 ℃ in air.The structure and morphology analysis show that MnCO3micro spheres are comprised with nanosized cubic.Mn2O3microspheres are constructed by nanosized particles.After mixing with Super P with different ratio,the electrochemical properties of Mn-CO3and Mn2O3were studied.The results exhibit that the specific capacitances of MnCO3and Mn2O3are significantly enhanced by mixing with Super P.When the ratio is 9:1,the maximum capacitance of MnCO3/Super P can reach 207 F·g-1,which is much higher than Mn2O3/Super P. |
