Herein, leaf-like CuO with mesoporous structure has been synthesized by treating commercial Cu(OH)(2) powder at room temperature for an appropriate time. The BET measurement shows that the obtained CuO has a high surface area of 23.55m(2) g(-1) and narrow pore distribution peaking at about 3.3 nm. The electrochemical performances of leaf-like mesoporous CuO are evaluated by cyclic voltammetry and galvanostatic charge-discharge studies. Electrochemical results show that the as-prepared CuO are promising anode materials in LIBs including high specific capacity, good retention and rate property. Even at the high current density of 2000mAg(-1), the mesoporous CuO electrode still can maintain a specific capacity of 490.5mAhg(-1) which is much higher than the theoretical specific capacity of graphite (372mAhg(-1)).
