Energy Storage: One‐Step Route Synthesized Co₂P/Ru/N‐Doped Carbon Nanotube Hybrids as Bifunctional Electrocatalysts for High‐Performance Li–O₂ Batteries (Small 30/2019)

In article number 1900001, Chengxiang Wang, Longwei Yin, and co-workers report a green protocol for in situ encapsulating Co2P and Ru nanoparticles into N-doped graphitic carbon nanotubes as a Li–O2 battery cathode. The homogeneously dispersed Co2P and Ru catalysts can synergistically induce the formation of large Li2O2 nanosheets coating layer with poorly crystallized and quasi-amorphous structure along the nanotube, constructing a homogenous and low-impedance interface between Li2O2/catalysts. Thus, the resulting hybrids effectively improve the oxygen redox kinetics of Li–O2 batteries.
