Abstract

In this work, we report a facile approach to synthesize uniform Co₃O₄ hollow spheres with tunable shell numbers via controllably annealing cobalt(ii) complex precursors at different heating rates. When evaluated as anodes for LIBs, the multi-shelled Co₃O₄ spheres exhibit high specific capacity, good rate capabilities and excellent cycling stability (1058 mA h g^-1 over 100 cycles at 1 A g^-1).
