It is essential to low cost electrode materials using facile method with good capacity and good cycling stability for lithium-ion batteries. We report easy method to synthesize a novel microporous and mesoporous cobalt based MOF requiring lower temperature and lesser reaction time. As binder free electrode for lithium-ion batteries, it exhibited a nominal high discharge capacity of 600 mAh g(-1) at 50 mA g(-1), and good cyclability with 99.8% coulombic efficiency. The observed enhancement of the electrochemical performance may be ascribed to the presence of micropores and mesopores of particles in materials, which provides enough space for storage and diffusion of the electrolyte. Thus, reported MOF electrode provides a great opportunity for energy storage materials. Moreover, MOF may be suitable template to design the define shape with pores of different metal oxide.
