Abstract

Anode based on conversion alloying reactions are considered one of the prospective electrodes in lithium (Li)-ion batteries (LIBs). However, the tremendous volume change upon cycling induces significant capacity decay. Herein, a common method has been implemented for the synthesis of SnWO₄ nanowires where bulky polyanions mitigate the structure stress. Thus, the SnWO₄ nanowires are examined as an anode material for LIBs, which demonstrate an initial discharge-specific capacity of 1211.4 mAh g^-1. In addition, the anode material is capable of delivering a stabilizing state capacity of almost 562 mAh g^-1 under the 1 A g^-1 current density after 100 cycles.
