However, rechargeable ZABs suffer from a limited cycle life. This paper reports that potassium persulfate (KPS) additive in an alkaline electrolyte can effectively enhance the performance and electrochemical characteristics of rechargeable zinc\u2013air flow batteries (ZAFBs). Introducing redox additives into electrolytes is an effective approach to promote battery performance. With the addition of 450 ppm KPS, remarkable improvement in anodic currents corresponding to zinc (Zn) dissolution and limited passivation of the Zn surface is observed, thus indicating its strong effect on the redox reaction of Zn. Besides, the addition of 450 ppm KPS reduces the corrosion rate of Zn, enhances surface reactions and decreases the solution resistance. However, excess KPS (900 and 1350 ppm) has a negative effect on rechargeable ZAFBs, which leads to a shorter cycle life and poor cyclability. The rechargeable ZAFB, using 450 ppm KPS, exhibits a highly stable charge\/discharge voltage for 800 cycles. Overall, KPS demonstrates great promise for the enhancement of the charge\/discharge performance of rechargeable ZABs.<\/jats:p>","DOI":"10.3390\/ijms21197303","type":"journal-article","created":{"date-parts":[[2020,10,3]],"date-time":"2020-10-03T07:22:16Z","timestamp":1601709736000},"page":"7303","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":62,"title":["Enhanced Cycling Performance of Rechargeable Zinc\u2013Air Flow Batteries Using Potassium Persulfate as Electrolyte Additive"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3081-3507","authenticated-orcid":false,"given":"Ramin","family":"Khezri","sequence":"first","affiliation":[{"name":"Department of Chemical Engineering, Faculty of Engineering, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soraya","family":"Hosseini","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering, Faculty of Engineering, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abhishek","family":"Lahiri","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering, Brunel University London, London UB8 3PH, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shiva Rezaei","family":"Motlagh","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering, Faculty of Engineering, Universiti Putra Malaysia, Selangor 43300, Malaysia"}],"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 for the Promotion of Business-Regional Collaboration, Hokkaido University, Sapporo 001-0021, Japan"}],"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":[[2020,10,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"372","DOI":"10.3389\/fchem.2020.00372","article-title":"Recent Progress in Electrolytes for Zn\u2013Air Batteries","volume":"8","author":"Chen","year":"2020","journal-title":"Front.
