Recent advances in producing hollow carbon spheres for use in sodium−sulfur and potassium−sulfur batteries
Sodium-sulfur (Na-S) and potassium-sulfur (K-S) batteries for use at room temperature have received widespread attention because of the abundance and low cost of their raw materials and their high energy density. However, their development is restricted by the shuttling of polysulfides, large volume expansion and poor conductivity. To overcome these obstacles, an effective approach is to use carbon-based materials with abundant space for the sulfur that has sulfiphilic sites to immobilize it, and a high electrical conductivity. Hollow carbon spheres (HCSs) with a controllable structure and composition are promising for this purpose. We consider recent progress in optimizing the electrochemical performance of Na-/K-S batteries by using these materials. First, the advantages of HCSs, their synthesis methods, and strategies for preparing HCSs/sulfur composite materials are reviewed. Second, the use of HCSs in Na-/K-S batteries, along with mechanisms underlying the resulting performance improvement, are discussed. Finally, prospects for the further development of HCSs for metal−S batteries are presented.
期刊介绍:
New Carbon Materials is a scholarly journal that publishes original research papers focusing on the physics, chemistry, and technology of organic substances that serve as precursors for creating carbonaceous solids with aromatic or tetrahedral bonding. The scope of materials covered by the journal extends from diamond and graphite to a variety of forms including chars, semicokes, mesophase substances, carbons, carbon fibers, carbynes, fullerenes, and carbon nanotubes. The journal's objective is to showcase the latest research findings and advancements in the areas of formation, structure, properties, behaviors, and technological applications of carbon materials. Additionally, the journal includes papers on the secondary production of new carbon and composite materials, such as carbon-carbon composites, derived from the aforementioned carbons. Research papers on organic substances will be considered for publication only if they have a direct relevance to the resulting carbon materials.
