Sb2S3 embedded in carbon–silicon oxide nanofibers as high-performance anode materials for lithium-ion and sodium-ion batteries

Based on the conversion and alloying reactions, antimony sulfide (Sb2S3) with a theoretical discharge specific capacity of 946 mAh g−1 is a hopeful anode material for lithium/sodium ion batteries. Nevertheless, the poor electronic conductivity of Sb2S3 and the serious volume expansion during alloying reaction bring about the rapid capacity fading, which severely hinder its practical application. The design of morphology/structure and/or...
