Transition metal oxides have shown extraordinary potential for lithium storage to date. Herein, a peony-like holey Co 3 O 4 architecture has been elaborately designed and successfully prepared via a solvothermal process followed by annealing treatment. The as-obtained peony-like Co 3 O 4 material sh...
