(189a) Development and Scale-up of a Novel Electrochemical Exfoliation Process to Manufacture Large Area, Few Atomic Layer, Defect-Free Graphene Flakes

In collaboration with the RAPID Manufacturing Institute® and with grant funding from the NIST Rapid Assistance (for) Coronavirus Economic Response (RACER) program, Avadain and Southwest Research Institute (SwRI) are developing and scaling a novel, environmentally-friendly electrochemical exfoliation process to convert graphite to fully reduced, large, thin and defect-free (LTDF) graphene flakes for a range of end use applications. In this presentation, the Avadain and SwRI team will describe development work to date to scale from bench to intermediate level batch production and provide insight into new patent-pending cathode assemblies that enable a step change in exfoliation productivity. The team will also offer plans for ongoing work to transition from batch to continuous exfoliation and will provide market context for the potential uses and value of LTDF graphene flakes versus other lower quality graphene offerings such as graphene oxide.
