To develop battery-supercapacitor hybrid devices with high energy and power densities, we propose a rational design of a quaternary hybrid superstructure by using a high-energy biotemplate. This new superstructure is composed of stable fullerene C₆₀ nanocages, electroactive Na₄FeO₃, high-energy Li₃V₂(PO₄)₃ and soft carbon as well as tubular ordered mesoporous channels. This design takes advantage of the unique properties of each component, resulting in nanocomposites with synergistic effects to improve the charge transfer and energy storage. We found that this quaternary hybrid electrode has both high energy and power densities as well as a long cycling life in a Li/Na mixed-ion electrolyte, outperforming a multitude of other battery-supercapacitor hybrid devices reported thus far. The charge storage mechanisms of this hybrid superstructure are proposed for optimizing the electrode design.

为了开发具有高能量和功率密度的电池-超级电容器混合装置，我们提出了使用高能生物模板的合理设计四元混合上部结构的方法。这种新的上层结构由稳定的富勒烯C ₆₀纳米笼，电活性Na ₄ FeO ₃，高能Li ₃ V ₂（PO ₄）_3组成。软碳以及管状有序介孔通道。这种设计利用了每种组分的独特性能，从而产生具有协同效应的纳米复合材料，从而改善了电荷转移和能量存储。我们发现，这种四元混合电极在锂/钠混合离子电解质中具有高能量和功率密度，以及长的循环寿命，胜过迄今为止报道的许多其他电池-超级电容器混合装置。提出了这种混合上部结构的电荷存储机制，以优化电极设计。
