Abstract:
1. A process for producing meso-porous nanocomposite supercapacitor electrode comprising nano-scaled graphene platelets, said process comprising: (A) Providing nano-scaled graphene platelets, wherein each of the platelets comprises a single graphene sheet or a stack of multiple graphene sheets, and the platelets have an average thickness no greater than 100 nm; (B) Combining a binder material, said graphene platelets, and a liquid to form a dispersion; (C) Forming said dispersion into a desired shape and removing said liquid to produce a binder-platelet mixture; and (D) Treating said binder material under a desired temperature or radiation environment to convert said binder-platelet mixture into said meso-porous nanocomposite electrode, wherein said platelets are bonded by said binder and said electrode has electrolyte-accessible pores characterized in that said nanocomposite has a surface area greater than about 100 m
