In article number 1900001, Chengxiang Wang, Longwei Yin, and co‐workers report a green protocol for in situ encapsulating Co 2 P and Ru nanoparticles into N‐doped graphitic carbon nanotubes as a Li–O 2 battery cathode. The homogeneously dispersed Co 2 P and Ru catalysts can synergistically induce the formation of large Li 2 O 2 nanosheets coating layer with poorly crystallized and quasi‐amorphous structure along the nanotube, constructing a homogenous and low‐impedance interface between Li 2 O 2 /catalysts. Thus, the resulting hybrids effectively improve the oxygen redox kinetics of Li–O 2 batteries.
