The explosive spherulites， characterized by their unique micro-nano multi-level structure， multiple grain boundaries， and macroscopic isotropy， present exceptionally advantages in terms of safety， mechanical properties， and energy release， making them a key focus in the morphological control of explosive crystals. This review introduces the concept， connotation， and morphological characteristics of spherulites， and summarizes the preparation methods， characteristics， and performances of the twelve reported explosive spherulites. Preparation techniques include solvent anti-solvent method， cooling method， melting method， membrane emulsification， microchannel technology， and solvent-thermal coupling reaction crystallization， among them the solvent anti-solvent method being the most prevalent. The formation process， morphological traits， and critical preparation factors of different spherulites are analyzed， while the interaction mechanisms among crystal structures， modifiers， and non-crystallographic branches are discussed. It also highlights the changes in safety， combustion performance， and mechanical properties， exploring the underlying reasons for these variations. In response to the current challenges in the development of explosive spherulites， relevant suggestions are proposed from six aspects： formation mechanism， characterization method， scale-up preparation， quality control， structure-activity relationship， and data modeling.
