Abstract

Abstract : In article number1900001, Chengxiang Wang, Longwei Yin, and co‐workers report a green protocol for in situ encapsulating Co2 P and Ru nanoparticles into N‐doped graphitic carbon nanotubes as a Li–O2 battery cathode. The homogeneously dispersed Co2 P and Ru catalysts can synergistically induce the formation of large Li2 O2 nanosheets coating layer with poorly crystallized and quasi‐amorphous structure along the nanotube, constructing a homogenous and low‐impedance interface between Li2 O2 /catalysts. Thus, the resulting hybrids effectively improve the oxygen redox kinetics of Li–O2 batteries.
