Fabrication of hierarchical porous MnCo2O4 and CoMn2O4 microspheres composed of polyhedral nanoparticles as promising anodes for long-life LIBs

Uniform mesoporous MnCo₂O₄ and CoMn₂O₄ microspheres that consist of numerous polyhedral nanoparticles were prepared and further evaluated as anode materials for lithium-ion batteries, which exhibited excellent long-life cycling stability at high rate density.
