Energetic ionic salts based on nitrogen-rich heterocycles are expected to usher in
a new era in the fields of propellants, explosives, and pyrotechnics owing to their excellent
combustion characteristics, green nature, and the ability to tailor them based on requirements.
The review focuses on an important aspect of these compounds, other than the synthesis
procedure and physico-chemical characterisation, that is frequently overlooked, i.e. the
decomposition pathways and the associated chemical kinetic parameters, which are essential
to elucidate and simulate their combustion characteristics. The reaction mechanisms of four
major families of energetic ionic salts, explored by various experimental and numerical
techniques, are reported in detail.
