Abstract

In this work, we have successfully grown single-crystalline nanoneedle arrays of NiCo ₂O ₄ on conductive substrates such as Ni foam and Ti foil through a simple solution method together with a post-annealing treatment. Remarkably, the NiCo ₂O ₄-Ni foam binder-free electrode exhibits greatly improved electrochemical performance with very high capacitance and excellent cycling stability.
