摘要：

High aspect ratio gamma-MnOOH nanowires (MNWs) are synthesized by a simple one-step hydrothermal method and used as catalysts in rechargeable nonaqueous lithium-oxygen batteries. When the nanowires are employed, great improvements in discharge capacity, cycle stability, and rate retention are obtained, which are attributed to the high catalyst efficiency and the cathode porosity.
