Reduced graphene oxide with 3D interconnected hollow channel architecture as high-performance anode for Li/Na/K-ion storage

Graphene is considered as one of the most promising anode materials for alkali (Li, Na and K) ion batteries in term of large specific surface area and high conductivity, whereas, low initial Coulombic efficiency, poor capacity and fast capacity decay severely block the commercialization process. Here, we designed reduced graphene oxide with three-dimensional interconnected hollow channel architecture (3D IH-rGO) via electrospinning/electrospray...
