摘要

通过氢键界面超组装合成球形碳超结构（SCS-6），具有表面开孔、通道互联和丰富的杂原子种类。最大化的表面活性位点的可及性和相反的电荷载流子存储机制确保了高的离子存储效率。基于SCS-6的组装锌离子混合电容器具有超高的能量密度（166 Wh kg−1）和超稳定的循环寿命（500,000次循环）。

Hydrogen-Bonded Interfacial Super-Assembly of Spherical Carbon Superstructures for High-Performance Zinc Hybrid Capacitors

Highlights

The spherical carbon superstructures (SCS-6) are synthesized by a hydrogen-bonded interfacial super-assembly, owning surface-opening pores, interconnected channels and rich heteroatom species.
Maximized accessibility of surface-active sites and opposite charge-carrier storage mechanism ensure high ion storage efficiency.
The assembled zinc-ion hybrid capacitor based on SCS-6 delivers ultrahigh energy density (166 Wh kg⁻¹) and super-stable cycle lifespan (500,000 cycles).

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
