Energetic materials are key basis materials in the national defense industry. However, realizing high power and low sensitivity at the same time has a great challenge and has not yet been broken through by merely relying on traditional design and synthesis of explosives due to the contradiction between energy and safety. The emerging and developing of energetic cocrystal materials provide a novel strategy to synthesize and tune properties for new high energy and low sensitivity explosives. This review introduces and discusses the development status of energetic cocrystal research, including design theory, preparation methods, property characterization and formation mechanism. This review also deeply summarizes and analyzes the facing main problems of the development for energetic cocrystal materials, such as lack of theoretical design, single preparation method and insufficient characterization analysis. Moreover, the development directions of energetic cocrystal materials are prospected, the future work should focus on the cocrystal intelligent design, high throughput screening, continuous preparation and microanalysis，in order to promote the energetic cocrystal materials development through extensive studies of relevant industries in our country.
