Abstract

ABSTRACT This article reports a strategy to use nitrogen-doped carbon materials as electrodes for supercapacitors. Depending on the carbon precursor, the porous structure is changed with specific surface area reached up to 2270 m2 g−1. The capacitance of carbon materials used as electrodes is related strictly to pore size. The microstructure and nitrogen functionalities enable a high capacitance (327 F g−1) and cycle durability. The nanoporous carbon electrode exhibits long-term cycle life and high cycle stability with a retention of 86% of its initial after 10,000 cycles in neutral electrolyte. Highly porous carbons are thus considered a promising material for supercapacitors. GRAPHICAL ABSTRACT

氮掺杂碳材料作为高稳定超级电容器的电极

摘要本文报道了一种使用氮掺杂碳材料作为超级电容器电极的策略。根据碳前驱体的不同，多孔结构发生变化，比表面积达到2270 m2 g−1.用作电极的碳材料的电容与孔径密切相关。微结构和氮功能实现了高电容（327 F g−1）和循环耐久性。纳米多孔碳电极表现出长期的循环寿命和高的循环稳定性，在中性电解质中10000次循环后，其保持率为初始值的86%。因此，高度多孔的碳被认为是一种很有前途的超级电容器材料。图形摘要

期刊介绍： Materials Research Letters is a high impact, open access journal that focuses on the engineering and technology of materials, materials physics and chemistry, and novel and emergent materials. It supports the materials research community by publishing original and compelling research work. The journal provides fast communications on cutting-edge materials research findings, with a primary focus on advanced metallic materials and physical metallurgy. It also considers other materials such as intermetallics, ceramics, and nanocomposites. Materials Research Letters publishes papers with significant breakthroughs in materials science, including research on unprecedented mechanical and functional properties, mechanisms for processing and formation of novel microstructures (including nanostructures, heterostructures, and hierarchical structures), and the mechanisms, physics, and chemistry responsible for the observed mechanical and functional behaviors of advanced materials. The journal accepts original research articles, original letters, perspective pieces presenting provocative and visionary opinions and views, and brief overviews of critical issues.
