Holey Nanocarbon Architectures for High-Performance Li-Air Batteries

Li-air batteries (LABs) have a theoretical energy density of 3500 - 5000 Wh/kg, nearly 10 times that of conventional Li-ion batteries (LIBs). A huge advantage is that the oxygen reactant at the cathode can be directly obtained from air (“air cathode”), thus significant cost and weight reduction of the battery can be obtained. However, major challenges remain for the LAB air cathodes, such as low catalytic efficiency and poor oxygen diffusion during long-term cycling.
