In the production of rechargeable ZIBs, the cathode plays an important role. Manganese oxide (MnO2) is considered the most promising and widely investigated intercalation cathode material. Nonetheless, MnO2 cathodes are subjected to challenging issues viz. limited capacity, low rate capability and poor cycling stability. It is seen that the MnO2 heterostructure can enable long-term cycling stability in different types of energy devices. Herein, a versatile chemical method for the preparation of MnO2 heterostructure on multi-walled carbon nanotubes (MNH-CNT) is reported. Besides, the synthesized MNH-CNT is composed of \u03b4-MnO2 and \u03b3-MnO2. A ZIB using the MNH-CNT cathode delivers a high initial discharge capacity of 236 mAh g\u22121 at 400 mA g\u22121, 108 mAh g\u22121 at 1600 mA g\u22121 and excellent cycling stability. A pseudocapacitive behavior investigation demonstrates fast zinc ion diffusion via a diffusion-controlled process with low capacitive contribution. Overall, the MNH-CNT cathode is seen to exhibit superior electrochemical performance. This work presents new opportunities for improving the discharge capacity and cycling stability of aqueous ZIBs.<\/jats:p>","DOI":"10.3390\/ijms21134689","type":"journal-article","created":{"date-parts":[[2020,6,30]],"date-time":"2020-06-30T16:06:54Z","timestamp":1593533214000},"page":"4689","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":70,"title":["MnO2 Heterostructure on Carbon Nanotubes as Cathode Material for Aqueous Zinc-Ion Batteries"],"prefix":"10.3390","volume":"21","author":[{"given":"Sonti","family":"Khamsanga","sequence":"first","affiliation":[{"name":"Department of Chemical Engineering, Faculty of Engineering, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5436-123X","authenticated-orcid":false,"given":"Mai Thanh","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Division of Materials Science and Engineering, Faculty of Engineering, Hokkaido University, Hokkaido 060-8628, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7371-204X","authenticated-orcid":false,"given":"Tetsu","family":"Yonezawa","sequence":"additional","affiliation":[{"name":"Division of Materials Science and Engineering, Faculty of Engineering, Hokkaido University, Hokkaido 060-8628, Japan"},{"name":"Institute of Business-Regional Collaborations, Hokkaido University, Hokkaido 001-0021, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0261-3014","authenticated-orcid":false,"given":"Patchanita","family":"Thamyongkit","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Faculty of Science, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rojana","family":"Pornprasertsuk","sequence":"additional","affiliation":[{"name":"Department of Materials Science, Faculty of Science, Chulalongkorn University, Bangkok 10330, Thailand"},{"name":"Center of Excellence in Petrochemical and Materials Technology, Chulalongkorn University, Bangkok 10330, Thailand"},{"name":"Research Unit of Advanced Materials for Energy Storage, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prasit","family":"Pattananuwat","sequence":"additional","affiliation":[{"name":"Department of Materials Science, Faculty of Science, Chulalongkorn University, Bangkok 10330, Thailand"},{"name":"Center of Excellence in Petrochemical and Materials Technology, Chulalongkorn University, Bangkok 10330, Thailand"},{"name":"Research Unit of Advanced Materials for Energy Storage, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adisorn","family":"Tuantranont","sequence":"additional","affiliation":[{"name":"National Science and Technology Development Agency, Pathumthani 12120, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siwaruk","family":"Siwamogsatham","sequence":"additional","affiliation":[{"name":"National Science and Technology Development Agency, Pathumthani 12120, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3129-2750","authenticated-orcid":false,"given":"Soorathep","family":"Kheawhom","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering, Faculty of Engineering, Chulalongkorn University, Bangkok 10330, Thailand"},{"name":"Research Unit of Advanced Materials for Energy Storage, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"15107","DOI":"10.1038\/s41598-019-51692-x","article-title":"Annealing induced a well-ordered single crystal \u03b4-MnO2 and its electrochemical performance in zinc-ion battery","volume":"9","author":"Corpuz","year":"2019","journal-title":"Sci.
