A green production of waste carbon to graphite(graphene) nanopowders
Summary The invention belongs to the field of low-temperature electrochemical graphitization and is improved by the FFC-Cambridge Process. In comparison to the traditional process, the invention can be at a low temperature of 850oC and shorter process time. This strategy can convert carbon blacks into high-value graphite (graphene). The method is simple, low temperature, without adding catalyzer, and low-cost. The products have a wide range of applications such as energy storage, catalysis, absorption, separation, processing metal cutter, precision die, aeronautics, and astronautics.

This invention can successfully convert hard carbon into high-value graphite (graphene). The invented process is simple, low-temperature, low-cost, and without the need of adding catalysts. The parameters of the process, including reduction potential, current density, temperature, molten salt, and additivities can artificial adjustment to modify the product of the physics and chemical property. Product including nanopowders, nanofibers, nanosheets, and hollow nanospheres can be with a wide range of applications.

The applications of graphitized carbon black through this process may aim at lithium-ion batteries-related materials (conductive additives, negative electrodes), energy storage (carbon-zinc batteries, fuel cells), industrial applications (refractory materials, steelmaking), general household applications (lubricants, colloidal graphite), military applications, diamond like coating, etc.
