Brief description of the institution:


The Instituto Nacional del Carbón (INCAR) is a research centre that belongs to the Consejo Superior de Investigaciones Científicas (CSIC), this latter being a Public Research Organism assigned to the Ministery of Economía y Competitividad. The INCAR is included into the area of Chemical Science and Technology, one of the eight research areas of the CSIC. At the present time, its main research lines are the development of carbon and inorganic materials for structural, energetic and environmental applications and coal conversion and clean technologies. The INCAR is formed by fifteen research groups, which are distributed in three Departments: Coal, energy and Environment, Chermistry of Materials and Chemical Processes and Environment.


Brief description of the Centre/Research Group (including URL if applicable):


Instituto Nacional del Carbón (INCAR-CSIC) is one of the 123 institutes of CSIC, ascribed to the area of Chemical Science and Technology. Current research interests encompass the development of nanostructured materials, whose structural, textural, electrochemical and catalytic properties are investigated for novel applications, going from energy conversion and storage to water remediation. Financial support is obtained from Local and National Research Programmes and European Programmes, as well as, industrial research contracts (Mining and Steel Industry, Coke and Tar Refining, Oil Companies). Over the years INCAR-CSIC has received funding for over 190 M Euro, including research projects and contracts.


The Group of Porous Functional Materials at INCAR-CSIC (www.incar.csic.es/porosos) has a widely recognized experience on research activities related to exploring carbon precursors (with special emphasis on/aiming at sustainability) and developing advanced carbon-based nanostructured materials for their use in high-tech applications. Our current research interests focus on the design and synthesis of nanoporous carbon/graphene materials as functional solids for their use as catalysts/electrocatalysts, adsorbents and electrodes in supercapacitors and Li-ion batteries. Part of the know-how acquired by the group in the last few years in relation to porous carbon synthesis and use as electrodes in supercapacitors and batteries is now being transferred to companies within the Energy field (under an H2020 project and research contracts).


Project description:


In order to be able to keep up with the increasing energy demand of electronic devices and enable the transition to a more sustainable society based on renewable energy, we must develop energy storage systems capable of reversibly and efficiently storing larger amounts of energy than current Li-ion batteries. Within this context, Li-Sulfur and Li-Selenium batteries are rising as a promising alternative. Both kinds of batteries allow storing up to 10 times the energy of current Li-ion batteries. However, their practical utilization is hindered by the low electronic conductivity of both elements and their discharge products, the volumetric expansion from S/Se to Li2S/Li2Se and the dissolution and shuttling of polysulfides/polyselenides.


This project will tackle the confinement of S/Se in the porous structure of carbon materials in order to alleviate the problems encountered by these types of batteries. Hence, the carbon material will act as conductive support for S/Se nanoparticles, its porous structure will allow confinement of the polysulfides/polyselenides which will restrict their shuttle and will also accommodate the volume expansion. Specifically, porous carbon materials will a hierarchical porosity combining interconnected pores of different sizes will be developed. S/Se will be confined in the smallest pores, whereas larger pores will provide quick access to the confined S/Se, so that the developed materials may provide not only large capacities, but also high rate capabilities. Tuning of the pore structure will be investigated in order to allow maximum loading of S/Se without compromising the electrochemical performance of the material. The synthesis of those materials will be carried out following sustainable and environmentally sound approaches.
