Ionic liquids are being considered as an alternative for Li-ion batteries electrolytes since many of them are non-flammable, which is one of the most problematic safety issues in Li-ion batteries [1-3]. In this particular case, we are investigating the solvation of lithium (Li+) in Ethylammonium Nitrate (EAN) [4-5] by means of first principles simulations and metadynamics simulations [6-8]. The structures of the local environment of the lithium cation and its coordination have been analyzed. The simulations show that the Li+cation undergoes different lithium coordination number with the nitrate ions. Analysis of the energy minima for the relevant lithium coordination is also discussed.
