Nanowire of WP as a High‐Performance Anode Material for Sodium‐Ion Batteries

Abstract

The design and development of electrode materials with high specific capacity and long cycling life for sodium‐ion batteries (SIBs) is still a critical challenge. In this communication, we report the development of tungsten phosphide (WP) nanowire on carbon cloth (WP/CC) as an anode for SIBs. The WP/CC exhibits superior sodium storage capability with 502 mA h g−1 at 0.1 A g−1. Moreover, this anode is capable of delivering a long lifespan at 2 A g−1 with an excellent capacity retention of 99 % after 1000 cycles.

Electrodeposited Binder‐Free Antimony−Iron−Phosphorous Composites as Advanced Anodes for Sodium‐Ion Batteries

“…Rechargeable SIBs or KIBs have been recognized as a promising substitute for LIBs because of their low cost, the abundance of Na, and high safety, and their energy storage mechanism is similar to that of LIBs . Continuous efforts have been devoted to developing suitable SIB anode materials, such as intermetallic alloys, hard carbon materials, and metal oxides, with high reversible capacities and excellent cycling stabilities . Nonetheless, progress in this aspect has been relatively slow.…”

[141][142][143][144][145][146][147][148][149][150] For example, due to the various oxidation states of vanadium, vanadium-based phosphides can exist in different phases, such as V 4 P 7 , VP 2 , VP 4 , and so on. Their potential as electrodes for energy storage has been revealed.…”

Ni2P Nanosheets on Carbon Cloth: An Efficient Flexible Electrode for Sodium-Ion Batteries

“…Although TMPs combined with the advanced carbon-based material could be a promising electrode for SIBs, the complex technological process limits their wide use. Recently, self-supported electrodes have been paid much attention for SIBs, especially the nanostructure directly developing on a substrate as a flexible electrode. − These advanced design strategies offer us an efficient additive-free electrode . We thus anticipate an enhanced electrochemical performance of SIBs by developing Ni 2 P on carbon cloth, which, however, has not been explored so far.…”
