Abstract: 
The void introduction for high-energy alloying-type electrode has suffered a dilemma between insufficient void leading to structural collapse and excessive void causing low volumetrical utilization ratio. Herein, a novel tunable void structure of SnO2-void-hierarchically vertical graphene (SnO2□hVG) nanoarray has been designed via facile C-plasma technique, which facilitates simultaneous encapsulation of protective vertical graphene and moderate void formation. Benefiting from the tunable void and interconnected highly conductive graphene shells and backbones, our all-in-one framework delivers excellent structural integrity and superior Li+ storage capabilities due to the precise volume buffering without collapse of structure and extravagant void. As a result, an imposing capacity of 650 mA h g−1 at 2 A g−1 and negligible capability degradation after 1000 cycles can be achieved. This result opens a new opportunity in tunable void design to enhance the electrochemical performance of alloying-type electrode materials.
