Hypergolic ionic liquids (HILs) are a family of promising green fuels among the liquid propellants. As compared to previous studies and mainly focusing on structural innovations and ignition improvement of anions, here a new strategy of introducing energetic nitrato group into the cationic framework is proposed and is aimed at providing additional oxygen in the fuel molecule to enhance the combustion performance of HILs. These newly developed nitrato‐functionalized HILs exhibit improved physical properties and combustion behavior including higher density, larger combustion flames, and longer combustion duration.
