  Graphene membrane,having a staggered multilayer structure,is demonstrated to be a promising membrane for energy storage and ion separation.The superior property of graphene membrane is owing to the exotic behaviour of fluid and ions confined in the graphene nanoslit(< 10 nm).Unlike the 1-D nanochannel in lab-on-a-chip devices,the graphene membrane has a unique cascading nano-slit system.Understanding of ion transport in graphene membranes is very limited.
