title: Oxygen bubble-templated hierarchical porous ε-MnO2 as a superior catalyst for rechargeable Li-O2 batteries.
abstract: Nickel foam-supported ε-MnO2 is synthesized through an oxygen-bubble template-assisted electrodeposition route and is applied as a new cathode catalyst for Li-O2 batteries. Owing to the 3D macro/micro/nano (multiscale) porous architecture, the prepared electrode exhibits low overpotential, high rate capability, and superior cycling durability.
