Abstract
Pole ear with film of hot-melt adhesive being covered is produced by sticking a lap of aluminum foil having film of hot-melt adhesive onto metal pole piece at position heat sealed by complex film of aluminum-plastic. Advantages of the invention are: guaranteeing seal of battery with no leakage, and easy of mass production.
Description
Technical field
The present invention relates to a kind of manufacture method of soft package lithium ion cell polar ear, belong to battery component.
Background technology
What be used at present that the housing of lithium ion battery encapsulation has is referred to as rigid package with what metallic aluminium or stainless steel or rigid plastics were made, the plastic-aluminum combined film production of usefulness that has be referred to as flexible package.Because flexible packing lithium ion battery in light weight, gravimetric specific energy is big, good insulating, and the low and manufacture method of cost simply and extensively is employed.But, be easy to cause battery drain because cementability is bad when the positive and negative electrode metal tabs of lithium ion battery and aluminum-plastic composite membrane heat seal.Domestic not good at present method solves, the lug and the supporting aluminum-plastic composite membrane that can only have blob of viscose from external import, therefore increased cost, the lug that has blob of viscose of domestic research is all undesirable, peels off easily under the immersion of electrolyte and causes battery drain.
Summary of the invention
Purpose of the present invention provides a kind of manufacture method of soft package lithium ion cell polar ear for the shortcoming that overcomes above-mentioned prior art just with deficiency, guarantee that battery does not leak thereby avoid peeling off.
The objective of the invention is to realize by following technical proposal:
The manufacture method of soft package lithium ion cell polar ear, it is characterized in that with the metal pole piece of plastic-aluminum packaging film heat-sealing position on paste the circle aluminium foil of hot melt adhesive film in addition with binding agent, promptly be made into the battery pole ear of hot melt adhesive film in addition.
Described binding agent is neoprene binding agent or acroleic acid binding agent or epoxy resin or silicone type binding agent; The internal layer that the aluminium foil of described tyre hot melt adhesive film also can remove outer protective film with the aluminum-plastic composite membrane of flexible-packed battery is the aluminium foil of hot melt adhesive film.
The lug that the present invention makes is being pasted the circle aluminium foil of hot melt adhesive film in addition with plastic-aluminum packaging film heat-sealing position, because the lug skin is that tightly heat seal is together for the hot melt adhesive film of hot melt adhesive film and aluminum-plastic composite membrane, thereby can guarantee the sealing of battery, and the cross section can not be subjected to peeling off between the immersion generation rete of battery electrolyte inside, and the metal covering of internal layer can be firmly on lug with cured binders, and the binding agent that adopts it in the immersion of electrolyte, do not dissolve, insoluble account and bonded thing do not peel off.
The lug that the present invention makes, the plastic-aluminum combined membrane material of also available flexible package removes outer protective film, and aluminium foil in the middle of exposing is coated bonding agent and is pasted a circle again in metal pole piece and aluminum-plastic composite membrane heat seal position exposing on the aluminium foil surface, and this material has same effect.
Can be with aluminium flake or nickel sheet or aluminium flake as the metal pole piece of battery pole ear.Can be according to the size of battery capacity, the processing different size.
Owing to take technique scheme to make this bright technology compared with the prior art have following advantage and effect:
A) on lug, paste a circle in addition hot melt adhesive film aluminium foil it can with the plastic-aluminum combined servant heat seal one tightly of flexible package, guarantee the sealing of battery and leakage accident do not take place;
B) manufacture method is simple, and raw material is easy to get, and be convenient to produce in batches, and cost is low.
