A facile hydrothermal fabrication was applied to hybridize in-site grown flower-like Ni-Fe layered double hydroxides (Ni-Fe LDHs) and carbon black (CB) nanoparticles. The well-conductive CB particles were dispersed homogeneously onto the petals of the Ni-Fe LDH flowers via a combination of electrostatic forces and ripening growth, and remarkably promoted the charge-transfer capability of the LDHs. The hybridized Ni-Fe LDH/ CB composite electrode exhibited excellent rate performance that retained both a high capacity and steady cycle life at a large charge-discharge current, and was highly competitive serving as a high-rate alkaline battery cathode.
