摘要
Antimony-based oxide anode shows high capacity but poor cycle performance. After introducing reduced graphene oxide (rGO), the cycle performances are significantly improved. However, special treatments are required for these composite. Herein, a room temperature, one pot synthesis of antimony oxide/reduce graphene oxide composite with addition of hydrazine hydrate is developed. In the synthesis, GO is reduced by hydrazine hydrate which also prevent the oxidation of Sb3+ to Sb3+. In addition, hydrazine hydrate efficiently suppresses the agglomeration of Sb2O3. The Sb2O3/rGO composite exhibits excellent rate capability and cycle performance owing to the good conductivity of rGO and strong chemical bonds between rGO and Sb2O3. (C) 2020 Elsevier B.V.
