In the prior art, the production of battery core generallys use electric resistance welding, ultrasonic bond and Laser Welding to weld the connection of each component Point, e.g., open (bulletin) number: CN107482156A (a kind of polymeric monomer lithium ion battery) is a kind of more satisfactory structure side Formula, but there is also deficiency in welding procedure, as described in it the upper tab of big battery core, lower tab respectively with the upper pole Otic placode, lower tab plate compress welding, mainly apply single-point high temperature to tab plate using Laser Welding and electric resistance welding in the prior art Fusing comes soldering polar ear and tab plate.These welding method energy consumptions are high, are easy rosin joint, dry joint, and contact surface is few, and resistance is big, operation Difficulty is high, and required equipment is more, and cost of investment is high.
Summary of the invention
For above-mentioned state of the art, technical problem to be solved by the present invention lies in provide a kind of battery, capacitor Welding method, by open (bulletin) number: based on the frame mode of CN107482156A (polymeric monomer lithium ion battery) a kind of, making It is hot-melted a kind of method of welding each component connection position of its battery core with soldering paste, solves easy rosin joint, dry joint, contact surface is few, electricity The problems such as big is hindered, is improved efficiency to realize, performance is improved, reduces equipment investment, energy consumption is reduced, reduces cost.
In order to solve the above-mentioned technical problem, the welding method of a kind of battery provided by the present invention, capacitor, with open (public Accuse) number: the frame mode preparation battery core and positive and negative electrode otic placode of CN107482156A.
Primary operational method: spare battery core, both ends are exposed the positive and negative tab that blank collector is used as.By positive plate, Diaphragm, negative electrode tab are rolled to be formed, and wherein negative electrode tab is coated with negative electrode active material, and in a side, there are small parts to be not coated with blank collection Fluid, when winding one it is exposed be used as negative electrode lug, positive plate is coated with positive electrode active materials, a side also there are small parts not Blank collector is applied, is used as anode ear other end is exposed when winding.Material safe temperature selected by battery core will be considered It is more than the fusing point of soldering paste.
Spare positive and negative electrode otic placode is one piece of planar set galvanic electricity pole plate, outside be furnished with electrode screw, be provided with above more A deflector hole is used for internal gas and is discharged and electrolyte is guided to enter with diversion groove, the deflector hole and diversion groove is furnished with To inside battery core.
Spare soldering paste, a kind of paste mixture being made of Alloy soldering powder, additive and scaling powder, fusing point It requires in the safe temperature of core material and diaphragm with welding temperature hereinafter, added with resinous matter in the additive, Surface is spilt into welding process in soldering paste, one layer of resin film is formed in pad surface after solidification and protects solder joint, prevent solder joint Oxidation, burn into electrolysis.
Concrete operations: one layer of soldering paste is coated in the welding surface of positive and negative electrode otic placode, is fixed respectively with the positive and negative tab of battery core Connection, then battery core is placed in constent temperature heater and is heated, when temperature be raised to soldering paste melting-point solder fusing, positive and negative tab and Positive and negative electrode otic placode welds together by heating fusing, the cooled and solidified of solder.
The constent temperature heater should be different from reflow soldering, and the heating method of constent temperature heater is that heat is first from positive and negative Step transmitting inside tab plate → soldering paste → positive and negative tab → battery core, soldering paste are welded in melting temperature fusing, battery core temperature Pyrolytic damage that may be present and unnecessary energy loss should be reduced below soldering paste fusing point.
It is in contrast to the prior art, the beneficial effects of the present invention are: making on core strueture more simply, welding process is more Add simple and fast, improve efficiency, pad is stronger, tight, comprehensive, increases the contact area between conductor, reduces resistance, mentions High-performance reduces equipment investment, reduces energy consumption, reduces cost.It can be allowed openly (bulletin) number using this welding method: CN107482156A (a kind of polymeric monomer lithium ion battery) is easier to implement, realize.
