The SAVE research project, Award for the Public-Private Collaboration Project.
Fernando Calle, professor at the ETSI of Telecommunications of the UPM, proposed the candidacy of SAVE (Energy Storage Systems based on Graphene for Electric Vehicles). Professor Calle leads this project that brings together researchers from the Institute of Optoelectronic Systems and Microtechnology (ISOM) of the UPM, the Higher Council for Scientific Research (CSIC) and the Repsol Technology Center. The objective is to contribute to the development of materials, technology and demonstrators based on graphene, within the Inspire Repsol-UPM program. This project demonstrated with four international patents the benefits that the new material allows to achieve in two types of energy storage devices: lithium ion batteries and supercapacitors.
Based exclusively on carbon atoms, a very light element with very strong atomic bonds, the extreme thinness of graphene gives it a huge surface area and transparency, and its electronic configuration gives it the highest known electrical conductivity. It joins such properties its mechanical and chemical stability against electrolytes. For this reason, graphene is an ideal material to manufacture light and high-performance energy storage systems, for application in electric vehicles or wearable electronics.
In addition to its activity in communications and biomedicine, the ISOM-UPM Graphene and 2D Crystals group continues its research for the generation and storage of renewable energy with the development of advanced micro-supercapacitors and the integration of graphene with solar cells, in collaboration with CIEMAT. In the first case, a laser is used to treat graphene oxide nanostructures, with which to reduce the size of the devices and increase their power density; in the second, monatomic layers of graphene are manufactured that are located in the active region of cells to improve their performance.
