“…More recently, alternative efforts to improve the kinetics of the S‐PAN redox reaction and battery performance have turned toward chemical doping instead. [ 185–191 ] Chalcogens like selenium (Se) and tellurium (Te), or even iodine atoms have been incorporated into the composite to accelerate reaction kinetics. For example, although sulfur is electrically insulating at room temperature with a conductivity of ≈5 × 10 −30 S cm −1 , elemental selenium is many orders of magnitude more conductive (in the order of 10 −5 S cm −1 ).…”

The increasing energy demands of society today have led to the pursuit of alternative energy storage systems that can fulfil rigorous requirements like cost‐effectiveness and high storage capacities. Based fundamentally on earth‐abundant sodium and sulfur, room‐temperature sodium–sulfur batteries are a promising solution in applications where existing lithium‐ion technology remains less economically viable, particularly in large‐scale stationary systems such as grid‐level storage. Here, the key challenges in the field are first highlighted, followed by comprehensive analyses of accessible strategies to overcome them, starting from engineering of the anode–electrolyte interface in both liquid and solid electrolytes. Recently reported polymer and solid‐state electrolytes are also surveyed. Thereafter, the core principles guiding use‐inspired design of cathode architectures, covering the spectrum of elemental sulfur and polysulfide cathodes, to emerging host structures, and covalent composites are focused upon. Future prospects are explored, with insights into other alkali‐metal systems beyond sodium–sulfur batteries, such as the potassium–sulfur battery. Finally a conclusion is provided by outlining the research directions necessary to attain high energy sodium–sulfur devices, and potential solutions to issues concerning large‐scale production, so as to ultimately realize widespread deployment of practical energy storage systems.

“…In view that high specific surface area may bring underwhelmed practical utilization of the electrode due to the excessive electrolyte consumption and low tap density, Pham et al. [ 190 ] reported a SeSPAN with only 12.13 m 2 g −1 by simple solution‐based blending approach. The resultant SeSPAN cathode with up to 63% mass loading exhibited a high energy storage efficiency in both Li and Na batteries.…”

Li‐chalcogen batteries, especially the Li–S batteries (LSBs), have received paramount interests as next generation energy storage techniques because of their high theoretical energy densities. However, the associated challenges need to be overcome prior to their commercialization. Elemental selenium, another chalcogen member, would be an attractive alternative to sulfur owing to its higher electronic conductivity, comparable capacity density, and moreover, excellent compatibility with carbonate electrolytes. Unlike LSBs, the research and development of Li–Se batteries (LSeBs) have garnered burgeoning attention but are still in their infant stage, where a comprehensive yet in‐depth overview is highly imperative to guide future research. Herein, a critical review of LSeBs, in terms of the underlying mechanisms, cathode design, blocking layer engineering, and emerging solid‐state electrolytes is provided. First, the electrolyte‐dependent electrochemistry of LSeBs is discussed. Second, the advances in Se‐based cathodes are comprehensively summarized, especially highlighting the state‐of‐the‐art SexSy cathodes, and mainly focusing on their structures, compositions, and synthetic strategies. Third, the versatile separators/interlayers optimization and interface regulation are outlined, with a particular focus on the emerging solid‐state electrolytes for advanced LSeBs. Last, the remaining challenges and research orientations in this booming field are proposed, which are expected to motivate more insightful works.

Sulfur (S) and selenium (Se) have been considered as promising high capacity cathode materials for rechargeable batteries. They have differencesintheir physical properties (e.g.,e lectronic conductivity) but the same number of electrons in their outermost shells,w hichl eads to similarity in their electrochemical behavior in batteries. In recent years, some efforts have been taken to combine them in electrodes in the hope of improved battery performance. The SÀSe bonds of these electrode materials lead to unusual properties and intriguing electrochemical behavior,w hich have attracted increasing interest. In thisM inireview,e lectrode materials containing SÀSe bonds are summarized, including inorganic S x Se y solid solutions, organic compounds, and organic-inorganic hybrid materials. Our understanding in these materials is still premature, but they have shown unique properties to be electrode materials. We hope this Minireview could provideanew insight into the design,s ynthesis, and understanding of thesem aterials, which could enable high energy density rechargeable batteries.
