electrochemical energy‐storage devices is one of the most appealing and emerging options. However, although ILs are hailed as safer and eco‐friendly electrolytes, to overcome the limitations imposed by the highly volatile/combustible carbonate‐based electrolytes, full‐scale and precise appraisal of their overall safety levels under abuse conditions still needs to be fully addressed. With the aim of providing

We applied DSC for the determination of enthalpies of synthesis reactions of pyridinium- and pyrrolidinium-based ionic liquids (ILs) from pyridine (or N-methyl-pyrrolidine) and n-alkyl bromides (with n = 4, 5, 6, 7, and 8). The combination of reaction enthalpy measurements by DSC with modern high-level first-principles calculations opens valuable indirect thermochemical options to obtain values of enthalpies of the formation and vaporization enthalpies of ILs.
