Facile synthesis of a mesoporous Co₃O₄ network for Li-storage via thermal decomposition of an amorphous metal complex

A facile strategy is developed for mass fabrication of porous Co₃O₄ networks via the thermal decomposition of an amorphous cobalt-based complex. At a low mass loading, the achieved porous Co₃O₄ network exhibits excellent performance for lithium storage, which has a high capacity of 587 mA h g^-1 after 500 cycles at a current density of 1000 mA g^-1.
