The urgent need for efficient energy storage systems has spotlighted supercapacitors and nanostructured porous carbon materials. These materials require structural optimization to enhance their performance and lifespan, necessitating advanced design and synthesis techniques. In a recent publication, Forse and co-workers reveal that structural disorder in nanoporous carbon materials significantly enhances their capacitance performance, suggesting that optimizing structural disorder is key to developing high-energy-density supercapacitors. This study innovatively shows that structural disorder in nanoporous carbon materials significantly enhances capacitance performance, surpassing traditional factors like pore size and surface area. The investigation of multiple nanoporous carbons from a range of different suppliers showcases the generalizability of the findings. Annealing treatment further confirms that the capacitance enhancement is due to structural disorder. This discovery guides the design and synthesis of new efficient electrode materials, providing a new direction for the future development of supercapacitors.
对高效储能系统的迫切需求使超级电容器和纳米结构多孔碳材料成为焦点。这些材料需要进行结构优化以提高其性能和使用寿命，这就需要先进的设计和合成技术。在最近的一篇出版物中，福尔西及其同事揭示，纳米多孔碳材料中的结构无序显著提高了它们的电容性能，这表明优化结构无序是开发高能量密度超级电容器的关键。这项研究创新性地表明，纳米多孔碳材料中的结构无序显著提高了电容性能，超过了孔径和表面积等传统因素。对来自一系列不同供应商的多种纳米多孔碳的研究证明了这些发现的普遍性。退火处理进一步证实，电容增强是由于结构无序。这一发现为新型高效电极材料的设计和合成提供了指导，为超级电容器的未来发展指明了新方向。
