The paper reports a kind of NiCo2O4 material with urchin-like morphology. This material was prepared using a facile strategy of hydrothermal process followed by calcinations, and exhibits an excellent electrochemical performance. For example, it delivers a specific capacitance high up to 1167[Formula: see text]Fg[Formula: see text] at 1[Formula: see text]Ag[Formula: see text] and still retains a value of 1095[Formula: see text]Fg[Formula: see text] at 10[Formula: see text]Ag[Formula: see text], showing a good rate capability; after suffering from 3000 cycles at 10[Formula: see text]A[Formula: see text]g[Formula: see text], the specific capacitance has only a decay of 12%, presenting a good cycling stability.
