Urchin-like NiCo2O4 particles were prepared by a facile hydrothermal method and conductive polypyrrole (PPy) coatings were formed on the surface of the NiCo2O4 particles by the chemical oxidative polymerization of pyrrole monomers. The effects of the PPy content on the electrochemical properties of the NiCo2O4/PPy composites were investigated. The 30 wt% NiCo2O4/PPy sample exhibited excellent electrochemical performance; the reversible specific capacity was 1164.9 mAh/g after 100 cycles at a current density of 200 mA/g, indicating an improvement in the electrochemical performance of the composite material.
