Sodium-ion capacitors (SICs) bridge the gap between batteries and supercapacitors. They combine the reactions of high-energy battery-type anodes and high-power capacitor-type cathodes, offering a potential solution to the limitations of both battery and supercapacitor technologies. However, in contrast to lithium-ion analogues that have been successfully commercialized, research on SICs is still in its infancy and requires significant attention to enable their use in practical applications. Consequently, the rational design of materials for SICs is still required in order to meet the increasing demands for SICs with superior energy and power performance and low cost. In recent years, a number of materials have been investigated to developing SICs that offer the aforementioned advantages, including superior electrochemical performance, low cost, good stability, and environmental friendliness. Herein, after a brief introduction to the principles of SICs, the recent developments on materials for SICs are summarized, including capacitor-type cathode, battery-type anode, and electrolytes, especially focusing on material design strategies as well as the relationship between structure and corresponding electrochemical performances. Furthermore, the regulatory aspects relating to the structure and composition of electrode materials for dual-carbon SICs are introduced. Finally, the challenges and opportunities for future developments in electrode and electrolyte materials for SICs are proposed, with the aim of guiding the scientific community in their future studies.</div></div>","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"78 ","pages":"Article 104285"},"PeriodicalIF":18.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This solvation structure allows improved oxidation stability up to 4.8 V (vs. Na⁺/Na), a high Na⁺ transference number, and the formation of a robust anion-derived solid-electrolyte interface (SEI), which facilitates Na⁺ migration to suppress the concentration polarization and achieves rapid de-solvation and diffusion of Na⁺ within the interface, resulting in significant improvement of rate performance and cycle stability.

To address these problems, an electrochemically induced rectification strategy is applied through a Fe ion electrolyte additive. Nickel hexacyanoferrate is selected as a model cathode. Pre- and post-cycling in the modified electrolyte (ME) revealed that the surface vacancies of the K_1.80Ni[Fe(CN)₆]_0.7498·2·51 H₂O (KNiHCF) are in-situ replenished with electroactive Fe ions and form a double-redox HCFs, resulting in enhanced conductivity and discharge capacity. Moreover, owing to the surface vacancy replenishment and gradient formation, the dissolution of KNiHCF in ME is decelerated. The resultant KNiHCF-ME cathode exhibits excellent rate performance (7000 mA g^-1) and cycling stability for both half (98.50 % after 1000 cycles at 1000 mA g^-1) and full (80.08 % after 5000 cycles at 2000 mA g^-1) cells.
