The invention discloses an anti-explosive easy-to-disassemble safe adhesive tape and a manufacturing method thereof. The adhesive tape comprises a flame-retardant, current-conducting, heat-conducting and heat-expansion pressure-sensitive adhesive layer, a flame-retardant, current-conducting, heat-conducting and extensible viscosity-losing layer, a flame-retardant, current-conducting, heat-conducting and heat-expansion pressure-sensitive adhesive layer, and a release material layer which are overlapped in sequence. By adopting the adhesive tape disclosed in the invention, a plurality of battery packs can be combined together to increase the capacity or voltage. If an automobile encounters a collision, the material of the adhesive tape is collided and heated, and then expands instantly in order to effectively separate each battery module, and avoid greater damage.
