Carbonized poly(vinylidene fluoride)/graphene oxide with three-dimensional multiscale-pore architecture as an advanced electrode material

A low-cost, mass-produced, dry-gel-based method for fabricating graphene based electroactive materials relevant to energy storage has been reported. This technique combines thermal decomposition of carbon-based materials for the formation of ultramicropores/micropores and freeze drying of graphene gels for the formation of mesopores/macropores. The as-fabricated pore-rich carbon materials show electrochemical performances with superior characteristics of stabilization, specific capacitance and rate capability, demonstrating their great potential applications in clean energy.
