Programmable coating of polyaniline on hemispherical nitrogen-doped mesoporous hollow carbon as high performance material for supercapacitor
Description
Miniaturized electronic and wearable devices require energy storage systems, which can store a large amount of energy in a very narrow space/volume. Supercapacitors are considered as promising devices for portable electronics due to their robust performance and ultra-high cycling stability; however, their volumetric capacitance is far from the reality. Herein, we have developed a hybrid of nitrogen-doped hemispherical structured carbon (HNC) and polyaniline (PANI). Synergistic contribution of pseudocapacitive PANI and electric double layer capacitive HNC results in remarkably improved electrochemical properties. An optimized HNC/PANI-0.05 composite displayed 16.19 times improvement in the volumetric capacitance (1263 F cm−3) and seven times in gravimetric capacitance (547 F g−1) than that of pure HNC. The composite also showcases improved energy, power density, and cyclic stability. Hence, in the HNC/PANI-0.05 composite achievement of a balance between the mesoporosity and high value density imparts a high gravimetric capacitance together with an excellent volumetric capacitance.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
