All-round utilization of resources is proposed for maximizing environmental and economic benefits. Herein, the concept of all-round utilization on biomass derivations applying to carbon-based supercapacitors is demonstrated. Orange peel is used for all subassemblies of supercapacitor, including electrodes, separator and electrolyte. A monolithic porous carbon (OPHPC) is prepared by one-step carbonization of orange peel and another composite electrode is further synthesized by a simple hydrothermal process, based on sufficient utilization of natural structure and chemical components. OPHPC exhibits a high specific surface area of 860 m² g⁻¹ and naturally doped nitrogen. The composite electrode shows the homogeneous and high mass loading of MnO₂. Orange peel also affords the role of separator benefited from the natural porous channel structure and high porosity of 74.6%. Orange peel juice is exploited to produce the electrolyte, and exhibits the best retention in natural separator. All-orange peel all-solid-state supercapacitor shows the high areal capacitance of 3987 mF cm⁻². Furthermore, the flexibility of orange peel is also utilized to achieve the shape-tailored monolithic porous carbon electrode and device, which further extends the utilized dimensionality in biomass applying to supercapacitors. The work starts with all dimensional utilization for biomass derived supercapacitor.

为了最大程度地提高环境和经济效益，建议对资源进行全面利用。在本文中，展示了对应用于基于碳的超级电容器的生物质衍生的全面利用的概念。桔皮用于超级电容器的所有子组件，包括电极，隔膜和电解质。通过充分利用自然结构和化学成分，通过橘皮的一步碳化来制备整体多孔碳（OPHPC），并通过简单的水热工艺进一步合成另一种复合电极。OPHPC具有860 m ²  g ^-1的高比表面积和自然掺杂的氮。复合电极显示出均匀且高质量的MnO ₂负载。橘皮还具有分离器的作用，得益于其天然的多孔通道结构和74.6％的高孔隙率。橘皮汁被用来生产电解质，并在天然分离器中表现出最佳的保留率。全橙皮全固态超级电容器显示出3987 mF cm ^-2的高面电容。此外，橘皮的柔韧性还用于实现形状定制的整体式多孔碳电极和装置，这进一步扩展了应用于超级电容器的生物质的利用尺寸。这项工作从生物质衍生超级电容器的全方位利用开始。
