氧化锰负载的茄基多孔碳电极材料的制备及性能研究

Preparation and Properties Study of Solagen-based Porous Carbon Electrode Materials Supported by Manganese Oxide

以茄子为原料,用碳化法制备了茄子碳前驱体(EC),之后采用KMnO_(4)浸渍和退火处理的方法制备了MnO@EC复合材料。通过XRD对材料进行表征并研究了其电化学性能。在1M的Na_(2)SO_(4)电解液中,MnO@EC 0.1在0.5A·g^(-1)时具有422.4 F·g^(-1)的比电容,5000次循环后MnO@EC 0.1仍具有89.8%的电容保持率。结果表明,MnO@EC复合材料可为高性能生物质炭基储能材料的研发提供新思路。

Eggplant carbon precursors(ECs)were prepared by carbonization applied eggplant as raw material.The MnO@EC composites were prepared by immersion in KMnO_(4) and annealing,its electrochemical properties were charactered by XRD and study.In a 1M Na_(2)SO_(4) electrolyte,the MnO@EC composite had a specific capacitance of 422.4 F/g at 0.5A/g and still had a capacitance retention of 89.8%after 5000 cycles.The results showed MnO@EC composites could provide a new ideas for the research and development of high-performance biochar-based energy storage materials.
