The production of graphene and its compounds

ProGraMass

Low Cost Graphene production

ProGraMass is focused on large scale production of graphene by Top-Down methodologies, basically tribology starting from graphite. One of the main drawbacks of this technology is that (few layer) graphene particle size is not homogeneous, i.e. the final product is polydisperse in terms of particle size, which might prevent the display of the desired properties.

Objectives

In this project we face two main objectives. First, how to isolate graphene from the reactants used for its preparation. We aim at recovering these products from the exfoliation process and reuse them. This will give us a more economic and environmentally friendly graphene exfoliation process. Once this is accomplished, the second big technologic challenge is how to obtain/separate graphene samples with a narrower particle size distribution so that we can measure and use their properties. In the project we plan to test several options to separate different graphene qualities. Additionally, this project presents other challenges: scaling up the quantity of graphene produced per batch to get a lab scale demonstrator, we will try to solve the inherent problems of the production process.

Finally, given the existence of many diverse applications, each requiring of different graphene qualities, we will focus our efforts on the preparation of graphene products best suited for electrochemical energy storage in the form of electrodes. We aim to study and optimize the graphene production for supercapacitors, batteries and/or hybrid systems.

Pedro Gómez-Romero is Full Professor of the Spanish National Research Council (CSIC) since 2006. He is the Head of the NEO-Energy Group at the Catalan Institute of Nanoscience and Nanotechnology, ICN2 (CSIC-BIST) in Bellaterra, Barcelona (Spain) (2007-).

Prof. Gomez-Romero research is focused on the design and development of materials for energy storage and conversion (lithium batteries, hybrid supercapacitors, flow cells, solar-thermal energy, nanofluids) including a wide variety of materials from inorganics (LiFePO4) to Graphene, with special emphasis on hybrid nanostructures and nanocomposite materials with inorganic clusters or nanoparticles and polymers or carbons. His most recent work focuses on Hybrid electrode materials and on novel Nanofluids for Heat Transfer in thermal-solar conversion and Electroactive Nanofluids for energy storage in flow cells. Also very recently, the creation of a spin-off company “Earthdas. Graphene mobility” aims at putting all the knowledge generated in the lab to work in the development of graphene-based energy storage devices
