Sodium intercalation and adsorption on graphitic carbon plays an important role in cathode wear during aluminium electrolysis and is relevant for sodium ion battery (NIB) applications. We present a parameter set for the ReaxFF formalism trained to describe sodium interactions with graphitic carbon. The force field developed reproduce the training data with(More)
We present chemically accurate potential energy curves of CH4, CO2 and H2 moving through hexagonal water rings, calculated by CCSD(T)/aug-cc-pVTZ with counterpoise correction. The barriers are extracted from a potential energy surface obtained by allowing the water ring to expand while the gas molecule diffuses through. State-of-the-art XC-functionals are(More)
