Mesoporous Co3O4 nanosheets-3D graphene networks hybrid materials for high-performance lithium ion batteries

- The mesoporous Co3O4 nanosheets-3D graphene networks have been found to display better LIB performance as compare with Co3O4/CNT and Co3O4 structures.
- Electrochemical impedance spectroscopy shows that the addition of 3DGN largely enhanced the electrochemical activity of Co3O4 during the cycling processes.
- The large specific surface area and porous nature of the Co3O4 nanosheets are very convenient and accessible for electrolyte diffusion and intercalation of Li+ ions into the active phases.
