Description
Technical field
The present invention relates to lithium ion power battery pole ear technical field, more particularly to pole needed for a kind of lithium-ion-power cell
The chip welding angle of attack manufacture craft of ear.
Background technology
Progress, scientific and technological development with society, environment and energy problem become increasingly conspicuous, and develop and popularize energy-conservation with new energy
The cry of source automobile is increasingly surging.Pure electric automobile and hybrid vehicle quickly grow as energy-saving automobile, at home and abroad have
Many money pure electric automobiles and hybrid vehicle are in volume production and sale.Vehicle mounted dynamic battery system is as pure electric automobile and mixes
One of core component of power vehicle is closed, its performance directly affects the performance and safety of pure electric automobile and hybrid vehicle
Property.The primary clustering of vehicle mounted dynamic battery system is lithium-ion-power cell.Lithium-ion-power cell is by multiple lithium ion batteries
Module is constituted, and each lithium ion battery module is stacked with multiple lithium-ion battery monomers.
At present, electric automobile (containing electrocar and electric bus) is with lithium ion battery (commonly referred to as " EV lithium batteries ")
It is driven, this lithium ion battery need to have more high magnification, more Large Copacity than the compact electric apparatus lithium ion battery such as regular handset,
Its using be characterized in groups use (typically single lithium-ion-power cell is simultaneously unified into group, meet output current it is big the need for,
Group is connected into big group, the need for meeting output voltage), the requirement to lithium-ion-power cell has two aspects extremely important：
1st, security, due to being to use in groups, any one lithium-ion-power cell in any group of lithium-ion-power cell occurs
Problem, can all influence the whole safety traffic of automobile, therefore, to the security requirement of each lithium-ion-power cell very
Height, 2, lithium-ion-power cell multiplying power is high, capacity big, adapts to high current charge and discharge.Therefore, lithium-ion-power cell draws
Line (also known as lug, point positive and negative pole, it will usually classified according to lug material, such as：Aluminium pole ears, nickel plating copper polar ear, nickel lug
Deng) width and thickness it is all more much larger than common compact electrical equipment or use for electronic products lithium ion power battery pole ear, common compact
, generally in below 10mm, thickness is 0.1mm or so for the width of electrical equipment or use for electronic products lithium ion power battery pole ear, and lithium from
The width of sub- electrokinetic cell lug is more than 35mm, and thickness is 0.1-0.6mm, and effect of the lug in lithium-ion-power cell is
Sealing, insulation and conduction.Its sealing and insulation are key performances, sealing and failure of insulation then whole lithium-ion-power cell
Failure.
The traditional structural design of lithium ion power battery pole ear is：Metallic conductor and solid-state including rectangular patch or web-like
The Sealant tabs of banding, after being heated through 140 degree~160 degree, are laterally bonded together (logical with metallic conductor upper and lower surface
Often claim heat-sealing).In order to ensure the performance of lug, it is necessary to keeping the profile of Sealant tabs can not have big in heat seal process
Change.Further, since the mobility of tab high temperature functional layer is poor with respect to the mobility of hot sealing layer, and fusing point will be higher by 30 DEG C
More than.Therefore, the tab after heat-sealing easily easily forms bubble with metallic conductor two sides, and metallic conductor thickness is thicker, gas
Bubble it is more serious, product rejection it is more.In addition, the metallic conductor thickness of lug is thicker, then metallic conductor two sides upper-lower position
The tab thickness at place is thinner, so as to influence the sealing property of lug.Moreover, for two end face (welding ends of metallic conductor
And exposed junction), i.e. its four angles due to very sharp, therefore in lug manufacturing process, easily mutually scratch metallic conductor or lug
Glue influences the presentation quality performance of product, so as to influence the yield rate of production and the normal service life of product.Importantly,
In lithium-ion-power cell manufacturing process, easily scratch or scratch the wrapping film of lithium-ion-power cell, thus influence lithium from
The security performance of sub- electrokinetic cell.
In addition, in traditional manufacture craft, having one kind is welded with applicator, but this heat-sealing method is to send out
Less, the temperature difference in heating area is bigger than normal for hot area, therefore is not suitable for using in lithium ion power battery pole ear field.
In addition, being typically all with the metallic conductor of web-like, again by spy after being sealed during volume production in traditional manufacture craft
Measured length cuts off metal tape conductor, but, this web-like technique can not realize one automated production, and intermediate demand is artificially held in the mouth
Operation is connect, and the finished product lug that the web-like technique is made has two problems, is first finished product lug out-of-flatness, next to that finished product
Many bad orders in lug.
