Abstract
本发明涉及一种热熔胶及含该热熔胶的软包装锂离子电池极耳，热熔胶由高熔点材料和热熔材料组构成，所述高熔点材料上、下表面分别复合所述热熔材料；含上述热熔胶的软包装锂离子电池极耳，包括所述热熔胶和极耳导电条，所述热熔胶复合在极耳导电条上。由于在高熔点的材料上、下面复合了热熔材料，在对电池进行热封时热熔材料可以具有流动性实现对电池极耳处的密封，高熔点材料不发生流动，可以防止热封时发生短路，形成具有防止短路功能的热熔胶。将这种热熔胶复合在极耳导电条上，对电池进行热封时不会因极耳处短路发生短路现象。适用于各种软包装锂离子电池。
The invention relates to a hot-melt adhesive and a soft-pack lithium-ion battery tab containing the hot-melt adhesive. The hot-melt adhesive is composed of a high-melting point material and a hot-melt material group, and the upper and lower surfaces of the high-melting point material are respectively compounded with the thermal Fusible material; the soft-pack lithium-ion battery tab containing the above-mentioned hot-melt adhesive, including the hot-melt adhesive and the tab conductive strip, and the hot-melt adhesive is compounded on the tab conductive strip. Since the hot-melt material is compounded on and under the high-melting point material, the hot-melt material can have fluidity to seal the battery tab when the battery is heat-sealed, and the high-melting point material does not flow, which can prevent heat sealing A short circuit occurs, forming a hot melt adhesive with the function of preventing short circuit. The hot-melt adhesive is compounded on the tab conductive strip, so that no short circuit will occur due to the short circuit at the tab when the battery is heat-sealed. Suitable for all kinds of flexible packaging lithium-ion batteries.
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.
