Our first task is to address the limitations found in the force field, based on the corrections previously suggested in the literature and taking AIMD calculations as reference. The strongest interactions among those which form the hydrogen bond network established in our system are the charge-dipole interactions, thus, the hydrogen bonds between the chlorine anion and the hydroxyl groups. In particular, in our system there are three di↵erent hydroxyl groups (see Figure ): the hydroxil in the carboxylic group of the LA, the alcohol group in LA, and the hydroxil group in choline, referred to as LACOOH, LAOH and ChOH respectively hereafter.
