Microfluidic-assembled hierarchical macro-microporous graphene fabrics towards high-performance robust supercapacitors

We develop a high-performance supercapacitor based on hierarchical porous graphene fabric with microfluidic assembly and chemical etching methods. Due to the open porous backbone, ordered pathway, large accessible surface, interfused network, high mechanical flexibility and mass production, the supercapacitors deliver high energy density, good capacitance, long-term washable/deformable stabilities, and can be implemented in wearable and self-powered applications.
