The advancement in the development of electrodes, especially cathodes for ARZIB, is faced with hurdles related to the shortage of host materials that support divalent zinc storage. Even the existing materials, mostly based on transition metal compounds, have limitations of poor electrochemical stability, low specific capacity, and hence apparently low specific energies. Herein, NH4V4O10 (NHVO), a layered oxide electrode material with a uniquely mixed morphology of plate and belt-like particles is synthesized by a microwave method utilizing a short reaction time (~0.5 h) for use as a high energy cathode for ARZIB applications. The remarkable electrochemical reversibility of Zn2+\/H+ intercalation in this layered electrode contributes to impressive specific capacity (417 mAh g\u22121 at 0.25 A g\u22121) and high rate performance (170 mAh g\u22121 at 6.4 A g\u22121) with almost 100% Coulombic efficiencies. Further, a very high specific energy of 306 Wh Kg\u22121 at a specific power of 72 W Kg\u22121 was achieved by the ARZIB using the present NHVO cathode. The present study thus facilitates the opportunity for developing high energy ARZIB electrodes even under short reaction time to explore potential materials for safe and sustainable green energy storage devices.<\/jats:p>","DOI":"10.3390\/nano11081905","type":"journal-article","created":{"date-parts":[[2021,7,25]],"date-time":"2021-07-25T22:07:00Z","timestamp":1627250820000},"page":"1905","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Microwave-Assisted Rapid Synthesis of NH4V4O10 Layered Oxide: A High Energy Cathode for Aqueous Rechargeable Zinc Ion Batteries"],"prefix":"10.3390","volume":"11","author":[{"given":"Seokhun","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering, Chonnam National University, Gwangju 61186, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0232-0705","authenticated-orcid":false,"given":"Vaiyapuri","family":"Soundharrajan","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Chonnam National University, Gwangju 61186, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sungjin","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Chonnam National University, Gwangju 61186, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Balaji","family":"Sambandam","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Chonnam National University, Gwangju 61186, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vinod","family":"Mathew","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Chonnam National University, Gwangju 61186, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jang-Yeon","family":"Hwang","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Chonnam National University, Gwangju 61186, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaekook","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Chonnam National University, Gwangju 61186, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"7795","DOI":"10.1021\/acs.chemrev.9b00628","article-title":"Active Materials for Aqueous Zinc Ion Batteries: Synthesis, Crystal Structure, Morphology, and Electrochemistry","volume":"120","author":"Jia","year":"2020","journal-title":"Chem.
