Construction of unique heterogeneous cobalt–manganese oxide porous microspheres for the assembly of long-cycle and high-rate lithium ion battery anodes

Porous (Co, Mn)(Co, Mn)₂O₄-based microspheres (CM-11-Ms) and core–shell microspheres (CM-11-CSMs) were firstly synthesized via controlled pyrolysis of CoMn-precursor microspheres at different temperatures under nitrogen, exhibiting advanced lithium storage capacities.
