To expedite the market adoption of SIBs, enhancing the energy density of SIBs is essential. Raising the operational voltage of the SIBs cathode is regarded as an effective strategy for achieving this goal, but it requires stable high-voltage cathode materials. Sodium iron sulfate (NFSO) is considered to be a promising cathode material due to its stable framework, adjustable structure, operational safety, and the high electronegativity of SO4\u2212. This paper reviews the research progress of NFSO, discusses its structure and sodium storage mechanism on this basis, and summarizes the advantages and disadvantages of NFSO cathode materials. This study also evaluates the advancements in enhancing the electrochemical characteristics and structural reliability of SIBs, drawing on both domestic and international research. The findings of this paper offer valuable insights into the engineering and innovation of robust and viable SIB cathodes based on NFSO at ambient temperatures, contributing to their commercial viability.<\/jats:p>","DOI":"10.3390\/nano14231915","type":"journal-article","created":{"date-parts":[[2024,11,28]],"date-time":"2024-11-28T09:21:23Z","timestamp":1732785683000},"page":"1915","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["A Comprehensive Review on Iron-Based Sulfate Cathodes for Sodium-Ion Batteries"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-3111-9669","authenticated-orcid":false,"given":"Yalong","family":"Zheng","sequence":"first","affiliation":[{"name":"School of Energy Sciences and Engineering, Nanjing Tech University, Nanjing 211816, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhen","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Molecular Engineering, Nanjing Tech University, Nanjing 211816, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinyu","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Energy Sciences and Engineering, Nanjing Tech University, Nanjing 211816, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Energy Sciences and Engineering, Nanjing Tech University, Nanjing 211816, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yichao","family":"Luo","sequence":"additional","affiliation":[{"name":"School of Energy Sciences and Engineering, Nanjing Tech University, Nanjing 211816, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaru","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Energy Sciences and Engineering, Nanjing Tech University, Nanjing 211816, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhoulu","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Energy Sciences and Engineering, Nanjing Tech University, Nanjing 211816, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1603-8623","authenticated-orcid":false,"given":"Yi","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Energy Sciences and Engineering, Nanjing Tech University, Nanjing 211816, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiang","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Energy Sciences and Engineering, Nanjing Tech University, Nanjing 211816, China"},{"name":"School of Chemistry and Molecular Engineering, Nanjing Tech University, Nanjing 211816, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5855-7766","authenticated-orcid":false,"given":"Baizeng","family":"Fang","sequence":"additional","affiliation":[{"name":"School of Chemical Engineering and Energy Technology, Dongguan University of Technology, Dongguan 523808, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e2307275","DOI":"10.1002\/smll.202307275","article-title":"A brief overview of silicon nanoparticles as anode material: A transition from lithium-ion to sodium-ion batteries","volume":"20","author":"Fereydooni","year":"2023","journal-title":"Small"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2200257","DOI":"10.1002\/smtd.202200257","article-title":"Fabrication of Na-ion full-cells using carbon-coated Na3V2(PO4)2O2F cathode with conversion type CuO nanoparticles from spent Li-ion batteries","volume":"6","author":"Subramanyan","year":"2022","journal-title":"Small Methods"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"105955","DOI":"10.1016\/j.nanoen.2021.105955","article-title":"A review of niobium oxides based nanocomposites for lithium-ion batteries, sodium-ion batteries and supercapacitors","volume":"85","author":"Yi","year":"2021","journal-title":"Nano Energy"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"2470258","DOI":"10.1002\/adfm.202470258","article-title":"Uniform Molecular Adsorption Energy-Driven Homogeneous Crystallization and Dual-Interface Modification for High Efficiency and Thermal Stability in Inverted Perovskite Solar Cells (Adv.
