The utility model discloses a nanometer micropore heat insulation sheet for a
power battery cell and a packaging jig of the nanometer micropore heat insulation sheet, the nanometer micropore heat insulation sheet comprises a first packaging film, a nanometer micropore heat insulation plate and a second packaging film, and the packaging jig comprises a jig bottom frame and a jig upper frame, the upper surface of the jig bottom frame is provided with a plurality of through first hollowed-out grooves and first
magnet grooves, limiting blocks are fixedly installed on the side faces of the jig bottom frame, second hollowed-out grooves are formed in the positions, corresponding to the first hollowed-out grooves, of the jig upper frame, and second
magnet grooves are formed in the positions, corresponding to the first
magnet grooves, of the jig upper frame. Magnets are fixedly mounted in the first magnet groove and the second magnet groove; according to the jig, the magnets are installed on the jig, the limiting blocks are installed on the jig bottom frame to limit the jig upper frame, and according to the principle of opposite attraction, the magnets on the two sides attract each other when the jig upper frame covers the jig bottom frame, so that the jig is not prone to sliding,
dislocation of the nanometer micropore heat insulation plate is avoided, and the reject ratio of production is reduced.
