Designing vertical channels with expanded interlayers for Li-ion batteries

Vertical channels with expanded interlayer spacing based on a MoS2/Gr/C composite have been designed. This structure can simultaneously shorten the pathway of Li-ion diffusion across the electrode and enhance the kinetics of Li-ion intercalation/deintercalation within the bulk electrode. Thus, it exhibits a high rate performance and long cycle life in Li-ion batteries.
