要旨

Potassium ion batteries (PIBs), characterized by the superiorities of low cost, moderate operating voltage and fast kinetics in electrolytes, are expected to narrow the gap between the energy storage systems based on abundant elements and lithium ion batteries (LIBs). However, the large size of K+ is not conducive to electrochemically reversible storage, limiting the practical application of PIBs. It is imperative to develop anode materials with salient performance for K+ storage. Bismuth-based materials stand out as promising candidate attributed to their low cost, high theoretical capacity, suitable reaction potential and large interlayer spacing. In this contribution, the recent research advances in Bi-based anode materials for PIBs, including metallic Bi-based materials and Bi-based compounds, are overviewed, focusing mainly on the K+ storage mechanisms and the relationship between the structure and performance of electrode materials. Particularly, the critical role of electrolyte optimization for Bi-based anode materials is emphasized. Finally, the prevailing challenges and prospects for the further development of Bi-based anodes are outlined. This review sets out to present a comprehensive knowledge of Bi-based anode materials for PIBs and stimulates further research towards practical applications.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive. Artificial photosynthesis Batteries Carbon dioxide conversion Catalysis Fuel cells Gas capture/separation/storage Green/sustainable materials Hydrogen generation Hydrogen storage Photocatalysis Photovoltaics Self-cleaning materials Self-healing materials Sensors Supercapacitors Thermoelectrics Water splitting Water treatment
