受复合材料设计的启发，我们提出了一种新的复合超级电容器，该电容器包括具有高功率和高能量相关电极材料的集成电池。复合电化学双电层电容器（EDLC）是功率P-1能量E-1的大功率EDLC和功率P-2能量E-2的大能量EDLC并联的等效电路。在本研究中提出并验证了一种用于设计功率P和能量E的专用复合超级电容器的方法，其中P-1/E-1>P/E>P-2/E-2。该方法在中型和大型专用复合超级电容器中进行了成功测试，这些超级电容器使用有机电解质以袋状电池的形式制造。与仅基于高功率或高能量相关电极材料的超级电容器相比，特定应用的复合超级电容器的重量减轻了40-60%。
Inspired by the design of composite materials, we propose a new composite supercapacitor that comprises an integrated cell with high-power- and high-energy-related electrode materials. The composite electrochemical double-layer capacitor (EDLC) is the equivalent circuit of a high-power EDLC of power P-1 and energy E-1 and a high-energy EDLC of power P-2 and energy E-2 connected in parallel. A methodology is proposed and validated in this study for the design of an application-specific composite supercapacitor of power P and energy E with P-1/E-1>P/E>P-2/E-2. The methodology was tested successfully in medium- and large-sized application-specific composite supercapacitors, which were fabricated in the form of pouch cells using an organic electrolyte. The application-specific composite supercapacitors offered weight reductions of 40-60% compared with supercapacitors based on the high-power- or on high-energy-related electrode materials only.
