Porous Co3O4 column as a high-performance Lithium anode material

Co3O4 has been widely investigated as a promising candidate anode material for lithium-ion batteries. We report on the porous Co3O4 column synthesized via a simple liquid phase method for reversible electrochemical lithium storage. The porous column structures are constructed by nanoparticles of 0.5 mu m -2 mu m in diameter. The porous structure improves the structure stability, shortens the diffusion path of ion/electron, and stabilize the interface of the electrolyte and active material. Impressively, a high discharge capacity of 992 mAh g(-1) is obtained at 200 mA g(-1) after 100 cycles. This implies the as-synthesized porous Co3O4 column demonstrates remarkable potential as an excellent anode material for lithium-ion batteries.
