摘要：
Submicron-sized Sb2O3 with hierarchical structure was successfully prepared via a synthesis of one-step solvothermal chemical route. Na-ion storage performance of Sb2O3 material was investigated. Sb2O3 anode exhibits a high reversible capacity (approximately 350 mAh/g) and stable cycle stability (greater than 95%) over 100 cycles at 100 or 200 mA/g. A full battery with Sb2O3 anode and P2-Na2/3Ni1/3Mn1/2Ti1/6O2 (PTO) cathode indicated a high energy density of 216.6 Wh/kg.
