The morphology of the as-synthesized HCuS@3D-CNF composite clearly revealed that the 3D-CNFs act as a basement for HCuS spheres. The electrochemical performance of as-synthesized HCuS@3D-CNFs was evaluated by cyclic voltammetry (CV) tests, gravimetric charge\u2013discharge (GCD) tests, and Nyquist plots. The obtained results revealed that the HCuS@3D-CNFs exhibited greater areal capacitance (4.6 F\/cm2) compared to bare HCuS (0.64 F\/cm2) at a current density of 2 mA\/cm2. Furthermore, HCuS@3D-CNFs retained excellent cyclic stability of 83.2% after 5000 cycles. The assembled asymmetric device (HCuS@3D-CNFs\/\/BAC) exhibits an energy density of 0.15 mWh\/cm2 with a working potential window of 1.5 V in KOH electrolyte. The obtained results demonstrate that HZnS@3D-CNF nanoarchitectonics is a potential electrode material for supercapacitor applications.<\/jats:p>","DOI":"10.3390\/ijms24119685","type":"journal-article","created":{"date-parts":[[2023,6,2]],"date-time":"2023-06-02T10:08:41Z","timestamp":1685700521000},"page":"9685","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Nanoarchitectonics of Three-Dimensional Carbon Nanofiber-Supported Hollow Copper Sulfide Spheres for Asymmetric Supercapacitor Applications"],"prefix":"10.3390","volume":"24","author":[{"given":"Miyeon","family":"Shin","sequence":"first","affiliation":[{"name":"Department of Energy Storage, Conversion Engineering of Graduate School, Jeonbuk National University, Jeonju 54896, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ganesh Prasad","family":"Awasthi","sequence":"additional","affiliation":[{"name":"Division of Convergence Technology Engineering, Jeonbuk National University, Jeonju 54896, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Krishna Prasad","family":"Sharma","sequence":"additional","affiliation":[{"name":"Division of Convergence Technology Engineering, Jeonbuk National University, Jeonju 54896, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4993-2066","authenticated-orcid":false,"given":"Puran","family":"Pandey","sequence":"additional","affiliation":[{"name":"Division of Physics and Semiconductor Science, Dongguk University, Seoul 04620, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1896-0558","authenticated-orcid":false,"given":"Mira","family":"Park","sequence":"additional","affiliation":[{"name":"Carbon Composite Energy Nanomaterials Research Center, Woosuk University, Wanju 55338, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7807-3272","authenticated-orcid":false,"given":"Gunendra Prasad","family":"Ojha","sequence":"additional","affiliation":[{"name":"Carbon Composite Energy Nanomaterials Research Center, Woosuk University, Wanju 55338, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1867-8034","authenticated-orcid":false,"given":"Changho","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Energy Storage, Conversion Engineering of Graduate School, Jeonbuk National University, Jeonju 54896, Republic of Korea"},{"name":"Division of Convergence Technology Engineering, Jeonbuk National University, Jeonju 54896, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2233","DOI":"10.1039\/D1EE03567C","article-title":"Flexible solid-state hybrid supercapacitors for the internet of everything (IoE)","volume":"15","author":"Lee","year":"2022","journal-title":"Energy Environ.
