摘要
非对称超级电容器(ASCs)是由两个不同的电极组成,因其可使器件的工作电压最大化,从而提高其能量密度,而备受关注。二氧化锰(MnO_(2))的理论比电容高、价格低、储量丰富和环境友好性等特征,是一种理想的超级电容器活性电极材料。本文综述了ASCs的组装原则及MnO_(2)水系、固态非对称超级电容器的研究进展,并展望了提高MnO_(2)基超级电容器能量密度的研究策略。
The asymmetric supercapacitor(ASC)is composed of two different electrodes.It has attracted much attention,because it can expend the working voltage and the energy density of the device.Manganese dioxide(MnO_(2))is characterized by high specific capacitance and their low-cost,abundance and environmentally friendly nature,have attracted significant interest as active electrode materials for supercapacitors.An introduction about the assembly principle of ASCs,MnO_(2) aqueous-based and solid-state ASCs,and the prospects for improving its energy density was given.
