Recent research has shown that small pore size and large thickness are critical requirements for high energy density supercapacitors. However, the effect of such changes are very interdependent and even conflicting. It is critical to understand how these electrode structural parameters affect the performance of supercapacitors and their charging dynamics. This thesis involves the investigation of multilayered graphene membranes (MGMs) as a unique physical model system to allow interpretation of the electrode parameters. It examines the effect of property variation on charging dynamics using a combination of experiments and modeling.
