TITLE

Enabling the green transition with graphene


Short Biography

Vittorio Pellegrini holds a PhD degree in condensed matter physics and he is currently the chief Executive Officer of Bedimensional Spa, spin-off of the Italian Institute of Technology. He is the head of division energy, composites and production of the European flagship project on graphene. He is also leader of the graphene flagship work-package energy storage. His current interests focus on the exploitation of two- dimensional crystals for energy devices and for applications in composites. Vittorio Pellegrini has published more than 180 peer-reviewed papers and he is co-inventor of several patents. He gave more than 100 invited/keynote talks. He was Fellow of the Italian Academy at Columbia University (USA) in 2008, Winner of Campisano prize for condensed matter physics of the Italian National Research Council in 2008. He has published several articles for the general public in newspapers and scientific magazines and routinely gives talks at science festivals and at other public events.

Abstract

In this talk I will discuss how graphene can be employed as a new material in the production of Li-based batteries. I will first highlight market needs and opportunities and then discuss the challenges related to the material production and quality certification [1]. I will present and discuss our activities, obtained in the framework of the European Graphene Flagship, leading to a hybrid anode material for lithium-ion batteries, encompassing silicon nanoparticles embedded onto graphene and synthesized via a scalable wet-jet milling method [2]. This synthesized composite, reinforced by a network of conductive carbon black exhibited electrochemical behavior that significantly supersedes the performance of a Si-dominant electrode structures [3].
