Nitrogen and sulfur co-doping carbon in different dimensions as electrode for supercapacitor applications
JOURNAL OF ALLOYS AND COMPOUNDS(2023)
摘要
At present, the designs of carbon nanomaterials are indispensable to fulfill the growing demand for high energy and power density of energy storage devices. Heteroatom-doped (such as B, N, O, P, S, etc) porous carbon has great potential in the application of supercapacitor (SC) electrode materials. Nitrogen-doped carbon (N-C) has displayed superior properties in SC applications, which has attracted the attention of researchers. Due to the synergistic effect between N and S atoms, the nitrogen and sulfur co-doped carbon (N/S-C) shows superior electrochemical properties compared to the nitrogen single-doped porous carbon. Therefore, the development of N/S-C as SC electrode is of great importance. In recent years, the literature on the study of N-C for SC applications has been very extensive, however, there are a limited number of review articles on N/S-C. This manuscript represents future research directions, recent developments in the pre-paration of N/S-C and its application in SC. Herein, the preparation and dimension structure of N/S-C were summarized. Finally, the electrochemical properties including specific capacitance (CF), energy density (ED) and power density (PD) are critically reviewed when these N/S-C are used as SC electrodes.(c) 2023 Elsevier B.V.
