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.
