Hollow Zn-doped Fe2O3 nanospheres were fabricated by a facile solvothermal method followed post-annealing treatment. The as-synthesized hollow have uniform size with diameter of about 200–500 nm. growth mechanism the was proposed based on many contrast experiments. Compared without Zn doping, showed an improved electrochemical performance in terms high rate capability and long cycling performance. At current densities 1 A g−1 2 g−1, exhibited initial capacity 861.5 698.4 mA h respectively, maintained at 580 470 after 500 cycles. These excellent properties can be attributed to unique nanostructure, doping makes crystal structure more stable during discharge/charge
