Energy and safety are the two most important concerns of energetic materials (EMs), while they usually contradict each other: the high energy typically goes together with low safety. Low sensitivity and highly energetic materials (LSHEMs) balance well the energy and safety and thus are highly desired for extensive applications. Nevertheless, on the whole, the energy–safety contradiction, the energy and component limits, and insufficient knowledge about the relationships among components, structures, and properties and performances of EMs have made the development of LSHEMs, or even the entire group of EMs, evolve slowly. This Perspective focuses upon the current progress in the clarifications of the energy–safety contradiction and the crystal packing–impact sensitivity relationship of EMs. Also, we propose strategies for creating new LSHEMs or desensitized EMs through crystal engineering, covering traditional EMs composed of neutral single-component molecules, energetic cocrystals, and energetic ionic sal...
