We report the fabrication of monolithic quasi-graphene film with porous carbon frameworks (GPF), both nitrogen-doped, by a one-step pyrolysis of commercial filter membrane, and demonstrate its improved performance in Li-ion storage compared to commercial graphite. Several advantageous features (porous framework and its integrity with the quasi-graphene, N doping) of this new electrode are manifested...
The synthesis of graphene in both high quality and quantity via economic ways is highly desirable and meaningful for practical applications. Here we report a simple, green and cost- effective multiple electrochemical exfoliation approach to high quality and high yield (nearly 50%) graphene flakes by using graphite rod from spent zinc–carbon as graphene source. The graphite rod (anode) and platinum...
