By comparing the differences in the physical and chemical properties, such as the enthalpy of formation and phase transition temperatures of the fluorinated/oxidized products of metal fuels, the characteristics and potential application advantages of fluorination energy release reactions in energetic systems were summarized. The research progress of composite energetic systems based on fluorinated oxidizers, including typical types and characteristics of fluorinated oxidants, as well as their applications in pyrotechnics, propellants, mixed explosives, and aluminum thermites has been reviewed. The research and development direction of the application of fluorine-containing oxidizers in composite energetic systems was prospected. It is pointed out that the systematic computational chemistry research on composite energetic systems based on different fluorine sources should be conducted to understand the thermodynamic and kinetic mechanisms of fluorination reactions and their structure-activity relationships at the atomic/molecular level. Furthermore, research should also be intensified on the fluorine transfer mechanism in combustion reactions and the interfacial fluorine infiltration mechanism under pre-ignition conditions. Based on this, new typical fluorine-containing oxidizers suitable for different scenarios should be developed from the view point of nano architectonics and reaction pathway design.
