Nickel-doped lithium-vacant layered LiyCr1−xNixO2: a potentially active electrocatalyst for the oxygen evolution reaction

Ni-doping in layered Li y Cr 1− x Ni x O 2 seems to be an effective technique to develop superior OER catalysts through an inductive effect of neighboring Cr–O and Ni–O bonds along with the partial Li-vacancy and cation mixing.
