Main research topics

Simulation of supercapacitors


We simulate systems consisting in ionic liquids electrolytes and carbon electrodes. We adopt a bottom-up strategy which consists in starting from a simple system with planar graphite electrodes before to tackle the more complex problem of realistic nanoporous electrodes. In our simulations we can apply a potential difference between the electrodes of the supercapacitor, which allows us to calculate the capacitances of the various setups.

Development of polarizable force fields


Many modeling problems in materials science involve finite temperature simulations with a realistic representation of the interatomic interactions. In ionic systems, it is possible to introduce physically motivated model potentials for the interactions, in which additional degrees of freedom provide a ¿cartoon¿ of the response of the electronic structure of the ions to their changing coordination environments. These potentials may then be parametrized by fitting the predicted forces and multipoles to a large body of information generated from DFT calculations. Such potentials are predictive, of first-principles accuracy, and have a high degree of transferability between different systems. In our laboratory we are currently developing such polarizable force fields for various systems such as ionic liquids or clays.
