Abstract
The present invention relates to a kind of thermosol and soft package lithium ion cell pole ear containing the thermosol. The thermosol consists of high smelting point material and thermal molten material covering the upper and lower surfaces of the high smelting point material. The soft package lithium ion cell pole ear includes the said thermosol and conducting strip with the thermosol compounded on. During thermal sealing the cell, the thermal mlten material with certain flowability to complete sealing while the high smelting point material without flowing avoid short circuit. The present invention is suitable for various kinds of soft package lithium ion cell.
Description
Technical field
The invention belongs to flexible packing lithium ion battery material applied technical field, particularly relate to a kind of hot melt adhesive and contain the soft package lithium ion cell polar ear of this hot melt adhesive.
Background technology
Present known soft package lithium ion cell polar ear does not possess the function that prevents battery short circuit with hot melt adhesive itself, and the lug that uses this hot melt adhesive to make does not possess the function of the short circuit of preventing equally.When being sealed, battery is short-circuited at the lug place easily.
Summary of the invention
The present invention is for solving the problem that exists in the known technology, when a kind of battery heat-sealing is provided the lug place be not short-circuited situation a kind of hot melt adhesive and contain the soft package lithium ion cell polar ear of this hot melt adhesive.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of hot melt adhesive is made of materials with high melting point and hot melt material group, is characterized in: the upper and lower surface of described materials with high melting point is compound described hot melt material respectively.
A kind of soft package lithium ion cell polar ear that contains above-mentioned hot melt adhesive comprises described hot melt adhesive and lug bus, and be characterized in: described hot melt adhesive is compounded on the lug bus.
The present invention can also adopt following technical measures to realize:
The hot melt adhesive characteristics are: described materials with high melting point is any one or two kinds of above mixtures in tetrafluoroethylene, polyester, polyimide, glass fibre, asbestos, silicon-dioxide, polyethylene, the polypropylene material.
The hot melt adhesive characteristics are: described hot melt material is one or more the mixture in modified polypropene, modified poly ethylene, vinyl acetate, terpene compound, rosin, the paraffin.
The hot melt adhesive characteristics are: the hot melt material of the upper and lower surface recombination of described materials with high melting point can be a commaterial.
The hot melt adhesive characteristics are: the hot melt material of the upper and lower surface recombination of described materials with high melting point can be different material.
The soft package lithium ion cell polar ear characteristics that contain above-mentioned hot melt adhesive are: described lug bus is any material in gold and silver, copper, aluminium, the nickel.
The soft package lithium ion cell polar ear characteristics that contain above-mentioned hot melt adhesive are: described lug bus is a carbon material.
The soft package lithium ion cell polar ear characteristics that contain above-mentioned hot melt adhesive are: described lug bus is a conducting polymer materials.
Advantage and positively effect that the present invention has are: since in dystectic material top and bottom compound hot melt material, hot melt material can have the mobile sealing that realizes the battery pole ear place when battery is sealed, materials with high melting point does not take place to flow and is short-circuited in the time of can preventing to seal, and forms the hot melt adhesive with the short-circuit function of preventing.This hot melt adhesive is compounded on the lug bus, can be when battery is sealed because of the lug place short circuit phenomenon that is short-circuited.

Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Embodiment 1: see also Fig. 1, at materials with high melting point 2 upper and lower faces difference composite hot melt materials A 1 and hot melt material B3, form anti-short circuit hot melt adhesive 5.Materials with high melting point 2 is any one or two kinds of above mixtures in the materials such as tetrafluoroethylene, polyester, polyimide, glass fibre, asbestos, silicon-dioxide, polyethylene, polypropylene.Hot melt material A1 and hot melt material B3 are any one or two kinds of above mixtures in modified polypropene, modified poly ethylene, vinyl acetate, terpene compound, rosin, the paraffin, hot melt material A1 and hot melt material B3 can be commaterials, also can be two kinds of different materials.
Embodiment 2: the anti-short circuit hot melt adhesive 5 described in the embodiment 1 is compound to constitute on the lug bus 4 prevents the short circuit lug.Lug bus 4 be in the metallic substance such as gold and silver, copper, aluminium, nickel any, or non-metallic material or conducting polymer materials such as carbon material.
Operating principle of the present invention is to form at materials with high melting point surface recombination hot melt material and prevent that short circuit hot melt adhesive, use are somebody's turn to do anti-short circuit hot melt adhesive and bus is formed lug.Hot melt material can have the mobile sealing that realizes the battery pole ear place when battery is sealed, and materials with high melting point does not take place to flow and is short-circuited in the time of can preventing to seal.
