1. A method of fabricating a cathode of an energy storage device, comprising:
combining a first portion of a porous carbon material and at least one component of a composite binder material to form a first mixture, wherein the at least one component comprises at least one of polyvinylidene fluoride (PVDF), a PVDF co-polymer, and poly(ethylene oxide) (PEO);
subjecting the first mixture to a high shear process; and
adding polytetrafluoroethylene (PTFE) to the first mixture after the subjecting step to form a second mixture.
