In Situ Growth of Novel Graphene Nanostructures in Reduced Graphene Oxide Microspherical Assembly with Restacking‐Resistance and Inter‐Particle Contacts for Energy Storage Devices

Graphene is extensively investigated for various energy storage systems. However, the very low density (<0.01 g cm −3 ) of graphene nanosheets has hindered its further applications. To solve this issue, a controlled assembly of 2D graphene building blocks should be developed into graphene microspheres with high packing density, and restacking of graphene should be prevented to ensure an electrochemically accessible surface area during the...
