摘要：

Cost-effective microsized NiCo2O4 electrode materials were synthesized via a facile and scalable galvanostatic deposition method followed by a simple thermal treatment. The obtained materials are typical secondary microsized particles composed of ultrafine cubic NiCo2O4 nanoparticles and have a high surface area and mesoporous structure. The microsized NiCo2O4 electrode shows an excellent cycling behavior with no capacitance decays and maintains a high performance (11.4 W h kg(-1) and 2404 W kg(-1) at 8 A g(-1)) even after 3000 cycles, indicating a promising candidate for practical applications in electrochemical capacitors.
