A method for preparing a heat insulation pad, the heat insulation pad and the battery

Abstract

This invention belongs to the field of battery technology and discloses a method for preparing a heat insulation pad, the heat insulation pad itself, and a battery. The method for preparing the heat insulation pad includes the following steps: S1, placing a support frame between a first mold and a second mold, closing the first mold and the second mold to obtain a molding cavity, injecting liquid silicone into the molding cavity, and then heating and pressurizing; S2, after molding, forming a silicone frame, opening the mold, and removing the support frame and the silicone frame; the silicone frame has several heat insulation core receiving holes, and the outer edge of the silicone frame is bonded to the inner edge of the support frame; S3, placing the heat insulation core in the heat insulation core receiving holes to obtain the heat insulation pad body; S4, covering the upper and lower surfaces of the heat insulation pad body with an encapsulation film, hot-pressing, and cutting to obtain the heat insulation pad. This invention's method for preparing the heat insulation pad can avoid deformation of the silicone frame and realize automated assembly line production of the finished heat insulation pad, thereby reducing assembly personnel, improving production efficiency, and increasing product qualification rate.
