The available volume in negative electrodes for cell stacks limits the totally energy-storing capability of these batteries. This paper introduces the first fully flowable Ce–metal flow battery operated with a semisolid, flowable anolyte. Using the semisolid fuel cell concept, we incorporate the sustainable and deposit-abundant features of non-Li-based batteries into the structure of RFBs to develop a fully flowable RFB system. Solid suspension electrodes of hydrophilic carbon particles deposited by earth-abundant metals with redox activity are investigated as alternatives to the redox-active molecules employed in typical RFBs to decouple the power delivery capability from the energy storage capacity in fully flowable RFBs. While being charged, earth-abundant redox-active metal (Cu, Pb or Zn) is electrodeposited on the carbon particle suspension, which is dissolved in the sequent discharging process. On the basis of the proposed contact-charge-transfer mechanism, the electrical contact to the solid suspension electrode is fed by the redox-inert hydrophobic current collector that restrains direct metal deposition on their surfaces due to the hydrophobicity.</p></div>","PeriodicalId":100036,"journal":{"name":"Advanced Sensor and Energy Materials","volume":"1 1","pages":"Article 100004"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773045X22000048/pdfft?md5=669f7277903a0c068c99251a82d4d92b&pid=1-s2.0-S2773045X22000048-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90256712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
