Abstract

Hierarchical nickel cobalt oxide (NCO) microspheres comprised of nanoscale mesoporous thorn arrays are developed as superior rate high capacity anodes in this work, i.e. 1063.3 and 860 mA h g-1at 180 and 4500 mA g-1, respectively. Stoichiometric urea serves as a selflate to favor the self-assembly of well-organized NiCo(OH)2CO3thorn microsphere precursors under an optimized hydrothermal reaction. The dispersed multi-phase hybrid crystal structure and the favorable specific surface area obtained during the controlled pyrolysis of NiCo(OH)2CO3microspheres markedly promote the cyclic stability of the single phase Ni1.5Co1.5O4.
