A flexible Sb2O3/carbon cloth composite as a free-standing high performance anode for sodium ion batteries.

A flexible Sb2O3/carbon cloth (CC) composite is synthesized using a simple solvothermal method. The Sb2O3/CC composite exhibits higher capacity and capacity retention of alloying and conversion reactions as an anode for sodium ion batteries, attributed to the good conductivity of CC and strong chemical bonds between Sb2O3 and CC.
