超级电容器因功率密度、能量密度较高,受到了广泛关注。Mn基化合物因具有环境兼容、易于获得,成本低、结构和形貌灵活,充放电速度快等优点,是理想的超级电容器电极材料。通过合成方法对Mn基电极材料的形貌进行调控,或者将其与合适的赝电容材料如金属化合物、硫化合物,以及碳基体系,如碳纳米管、石墨烯等复合,提高Mn基化合物的比电容。综述了Mn基电极材料的制备方法、形貌、与其他材料复合方面的研究进展。
Supercapacitors with high power density and energy density have attracted widely attention.Mn-based compounds are ideal electrode materials for supercapacitors because of their environmental compatibility,ease of availability,low cost,flexible structure and morphology,and fast charge-discharge rates.In order to improve the specific capacitance of Mn-based compounds,the morphology of Mn-based electrode materials is regulated by synthesis method or by combining them with appropriate pseudocapacitive materials such as metal compounds,sulfur compounds,and carbon-based systems such as carbon nanotubes graphene.In this work,the research progress on preparation methods,morphologies,and compounding with other materials of Mn-based electrode materials were reviewed.
