Abstract

Hollow cupric oxide (CuO) spheres are successfully prepared via annealing a mental-organic framework precursor (HKUST-1). As novel anode materials for sodium ion batteries, the as-prepared CuO delivers high initial reversible capacity of 612 mAh g⁻¹ and good capacity retention of 83% after 50 cycles with superior rate capability.
