NOVELTY - The utility model claims a soft package lithium ion battery aluminium plastic film, comprising a bioplastics outer protection layer, the first adhesive layer, the first graphene film layer, the second adhesive layer, the first low pressure cold spraying aluminium layer, an aluminium foil layer, a second low-pressure cold spraying aluminium layer and CPP heat sealing layer. The utility model claims a soft package lithium ion battery aluminium plastic film, the graphene film with good mechanical property and improve the radiating performance so as to improve the service life and safety of the battery can heat to aluminum brings better flexibility, reduces the danger coefficient; it can realize good deep punching moulding property, compared with other techniques, low pressure cold spraying aluminium has better operability, and can further reduce the thickness of the aluminum foil, that is, reduce the usage amount of aluminium, reducing the presence of pinholes, which further enhances the barrier property and tightness of the plastic film.
