In article number 2004925, Yan Yu, Yanglong Hou, and co‐workers report a hierarchical porous Na3V2(PO4)2O2F hollow nanosphere material with fast ionic/electronic conductivities, easy and continuous electrolyte supplement and robust electrode integrity properties, kinetically accelerated sodium‐ion storage behavior of high‐capacity, high‐rate and long‐life cycling.
Sodium‐ion batteries (SIBs) are receiving considerable attention as economic candidates for large‐scale energy storage applications. Na3V2(PO4)2O2F (NVPF) is intensively regarded as one of the most promising cathode materials for SIBs, due to its high energy density, fast ionic conduction, and robust Na+‐super‐ionic conductor (NASICON) framework. However, poor rate capability ascribed to the intrinsically...
In article number 1901995, Yanglong Hou and co‐workers demonstrate a simplistic, scalable and general synthesis strategy employing various combinations of binary transition metal selenides (B‐TMSs) with high surface area and hierarchical nanosheet structures as promising anodes for sodium ion batteries (SIBs). Representative B‐TMSs anodes present adequately high energy capacities, excellent rate capabilities...
Multiple transition metals containing chalcogenides have recently drawn boosted attraction as anodes for sodium ion batteries (SIBs). Their greatly enhanced electrochemical performances can be attributed to the superior intrinsic conductivities and richer redox reactions, comparative to mono metal chalcogenides. To employ various binary metals comprising selenides (B‐TMSs) for SIBs, discovery of a...
Owing to high energy capacities, transition metal chalcogenides have drawn significant research attention as the promising electrode materials for sodium‐ion batteries (SIBs). However, limited cycle life and inferior rate capabilities still hinder their practical application. Improvement of the intrinsic conductivity by smart choice of elemental combination along with carbon coupling of the nanostructures...
