摘要：

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)).
