Problems solved by technology

[0002] The lithium battery packaging film of the prior art is generally made up of nylon layer, aluminum foil layer and heat-sealing layer, can adopt dry process or thermal process to prepare lithium battery packaging film during preparation, the performance of lithium battery packaging film is good or bad to lithium battery. The service life is closely related. High barrier and corrosion resistance are the basic functions that lithium battery packaging films must have. The current lithium battery packaging films are good in terms of barrier properties, but not good in corrosion resistance. Corrosion of lithium batteries is relatively common and needs to be further improved

Embodiment Construction

[0031] In order to understand the technical scheme of the present invention more intuitively and completely, the non-restrictive feature descriptions are now carried out in conjunction with the accompanying drawings of the present invention as follows:

[0032] Such as figure 1 As shown, the barrier and corrosion-resistant lithium battery packaging film includes nylon layer 1, aluminum foil layer 3 and heat seal layer 6, and it also includes outer graphene layer 2, inner graphene layer 4 and silicone rubber layer 5, nylon layer 1, The outer graphene layer 2, the aluminum foil layer 3, the inner graphene layer 4, the silicone rubber layer 5 and the heat-sealing layer 6 are distributed sequentially from outside to inside.

[0033] Nylon layer 1 is composed of the following raw materials in mass percentage: MXD6 57%, glass fiber 30%, LLD PE-g-MAH 9.5%, nano silicon dioxide 3%, silane coupling agent 0.3%, hydroquinone 0.2% ;

[0034] The heat-sealing layer 6 is made up of the fo...

Abstract

The invention discloses a high-barrier corrosion-resistant lithium battery packaging film, which comprises a nylon layer, an aluminum foil layer and a heat-seal layer, and further comprises an outer graphene layer, an inner graphene layer and a silicone rubber layer, wherein the nylon layer, the outer graphene layer, the aluminum foil layer, the inner graphene layer, the silicone rubber layer andthe heat-seal layer are sequentially distributed from outside to inside, the nylon layer is prepared from MXD6, glass fibers, LLDPE-g-MAH, nanometer silicon dioxide, a silane coupling agent and hydroquinone, and the heat-seal layer comprises polypropylene, glass fibers, nanometer calcium carbonate, talcum powder and barium sulfate. The high-barrier corrosion-resistant lithium battery packaging film has good corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of lithium battery packaging films, in particular to a high-barrier, corrosion-resistant lithium battery packaging film and a preparation method thereof. Background technique [0002] The lithium battery packaging film of the prior art is generally composed of a nylon layer, an aluminum foil layer and a heat-sealing layer. During preparation, a dry process or a thermal process can be used to prepare the lithium battery packaging film. The performance of the lithium battery packaging film has a great impact on the performance of the lithium battery. The service life is closely related. High barrier and corrosion resistance are the basic functions that lithium battery packaging films must have. The current lithium battery packaging films are good in terms of barrier properties, but not good in corrosion resistance. Corrosion of lithium batteries is relatively common and needs to be further improved. Contents...
