A Hierarchical Layering Design For Stable, Self-Restrained And High Volumetric Binder-Free Lithium Storage

A hierarchical layering strategy is developed for silicon anodes. The resultant parallelly oriented graphene-sandwiched layered silicon/graphene hybrid microparticles exhibit stable cycling with high volumetric capacity when being charged and discharged at high rates and commercial loading levels, attributable to the designed architecture.
