The utility model discloses an aluminum
plastic film edge sealing structure for
solid-state battery and aluminum
plastic film composite production device, and aluminum
plastic film includes first unit membrane and second unit membrane along the fold line, and first unit membrane is provided with electric core containing groove, and second unit membrane cover is established in the
notching of electric core containing groove, and the side of electric core containing groove is sealed edge, and sealed edge comprises heat seal layer,
aluminum foil layer and outer
surface layer who are stacked in turn from inside to outside, the surface of heat seal layer away from
aluminum foil layer is provided with concave-convex grain, and the surface of outer
surface layer away from
aluminum foil layer corresponding to first unit membrane is provided with bending groove, and the extension direction of bending groove is consistent with the length direction of sealed edge. Through the surface of heat seal layer away from aluminum foil layer is provided with concave-convex grain, effectively solve the misplacement of folding aluminum plastic film and lead to sealed edge misalignment, not only influence the appearance and size of battery, also influence the tightness of sealed edge, through the setting of bending groove, sealed edge bending resistance improves, is more docile, improves the tightness of sealing and battery size stability.
