The embodiment of the invention discloses a preparation method of a battery cell spacing heating pad and a heat insulation pad. The preparation method comprises the following steps: cutting aerogel, cutting a PET (Polyethylene Terephthalate) film, internally mixing silica gel, slitting the silica gel, molding the silica gel, cutting an inner frame, assembling, pressing, trimming and pasting a double-sided adhesive tape. In the assembling step, the treated PET film is attached to the surface of the inner frame of the silica gel finished product to obtain the assembled finished product, the coating machine is adopted for treatment, and the coating layer is attached to the surface of the PET film, so that an adhesive treating agent does not need to be smeared on the surface of the PET film in the assembling process, the preparation procedures are reduced, the process complexity is reduced, and the production efficiency is improved. And the problem that the adhesive treatment agent is not uniformly ...
