Abstract
The invention provides a lithium battery pack packaging material, which has a mesh structure, and is synthesized by aramid fiber powder and a pvc pyrocondensation material, wherein the mass ratio of the aramid fiber powder to the pvc pyrocondensation material is (1:1) to (1:3). The invention provides the lithium battery pack packaging material. Due to the mesh structure, the heat dissipation performance of lithium batteries is relatively good; and the defect of heating of the batteries is remedied. A composite material is prepared from aramid and pvc, so that the strength of a packaging film is increased; a direct protection role can be put into a play; damages caused by explosion of the batteries are avoided; and the defect that the lithium batteries are explosive is remedied.
Description
Technical field
The present invention relates to field of packaging material, be specifically related to a kind of lithium battery group packaging material.
Background technology
" lithium battery " is a class is negative material, the battery using non-aqueous electrolytic solution by lithium metal or lithium alloy.Lithium battery volume is little, and capacity is large, and voltage stabilization, can recycle, high safety, and this is the fastest, and decreasing pollution is conducive to sustainable development.The packaging material that the lithium battery that exists in the market uses mostly are pvc heat-shrinkable T bush, without gas permeability and also material comparatively fragile, be unfavorable for transport and the carrying of lithium battery group.
Summary of the invention
The invention provides a kind of lithium battery group packaging material, be unfavorable for the gas permeability and material fragility that solve prior art existence the problem that lithium battery group is transported.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of lithium battery group packaging material, have network structure, synthesized by aramid fiber powder and pvc material contracting with heat, the service quality ratio of aramid fiber powder and pvc material contracting with heat is between 1:1 ~ 1:3.
The service quality ratio of above-mentioned aramid fiber powder and pvc material contracting with heat is 1:2.
The production technology of above-mentioned lithium battery group packaging material, with aramid fiber powder and pvc material contracting with heat for raw material, by aramid fiber powder and pvc material contracting with heat according to after about ratio uniform mixes, fuse at 120 DEG C of temperature He under 14 MPa, then form netted plate through moulding press compacting.
The invention provides a kind of lithium battery group packaging material; network structure makes the heat dispersion of lithium battery better; compensate for the defect of battery-heating; aramid fiber and pvc is adopted to form composite material; add packaging film strength; can direct protective action be played, avoid the damage that battery explosion causes, compensate for the shortcoming that lithium battery is explosive.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of aluminum cell group packaging material of the present invention.
Embodiment
As shown in the figure, a kind of lithium battery group packaging material, there is network structure, synthesized by aramid fiber powder and pvc material contracting with heat, the service quality ratio of aramid fiber powder and pvc material contracting with heat is 1:2, the production technology of lithium battery group packaging material, with aramid fiber powder and pvc material contracting with heat for raw material, by aramid fiber powder and pvc material contracting with heat according to after about ratio uniform mixes, fuse at 120 DEG C of temperature He under 14 MPa, then form netted plate through moulding press compacting.
