This invention discloses a heating-not-burning cigarette cooling unit containing a phase change cooling material and a heating-not-burning cigarette. The unit comprises at least a carrier paper and a phase change cooling material coated on the carrier paper. The phase change cooling material is distributed in a non-fully-covering, regular pattern on the carrier paper. The carrier paper coated with the phase change cooling material forms multiple longitudinally extending channels through winding, folding, gathering, bending, and wrinkling, and has a porosity of 40%-90% along the longitudinal direction. The phase change cooling material comprises 55-96 parts by weight of polyethylene glycol, 1-5 parts by weight of in-situ reinforcing material, and 3-40 parts by weight of thermally conductive filler. The heating-not-burning cigarette cooling unit of this invention has the advantages of high latent heat of phase change, low thermal hysteresis effect, high heat absorption efficiency, apparent stability without collapse, and no leakage.

The invention relates to a composite metal foil with high peel strength, a metal-clad laminated plate and a battery. The high-peel-strength composite metal foil comprises a base film layer and a metal layer, the metal layer is arranged on at least one side face of the base film layer, a plurality of protrusions are arranged on the side face, close to the base film layer, of the metal layer, the height of the protrusions is 0.5-5 micrometers, the protrusions comprise the first protrusions and the second protrusions, the height of the first protrusions is 1.5-5 micrometers, the height of the second protrusions is 1.5-5 micrometers, and the height of the second protrusions is 1.5-5 micrometers. The height of the second protrusions ranges from 0.5 micrometer to 1.5 micrometers. Wherein the second protrusions are arranged between at least 40% of the adjacent first protrusions. The overall design is beneficial to improving the interlayer binding force between the metal layer and the base film layer, the delamination resistance of the composite metal foil can be improved, the working safety of the lithium battery can be improved, meanwhile, the bonding stability of a circuit and the metal foil can be improved when the composite metal foil is used for circuit manufacturing, and the circuit manufacturing quality can be improved.
