18650 Lithium Ion Battery Welding Method, Lithium Ion Battery Processing Welding Process. Power 18650 Lithium-ion battery manufacturing process welding method and process reasonable selection, will directly affect the cost, quality, safety, and battery consistency, and the welding of lithium ion batteries is used to welding, compared to the traditional welding method, laser welding process. Horizontal, effectiveness is also considerable, and security issues are better resolved.
18650 Lithium Ion Battery Welding Method We understand that the outer casing of the 18650 lithium-ion battery is a steel shell, no dedicated battery spot welding machine, which is difficult to weld by electric soldering. Of course, there is also a powerful battery flux, which can be easily welded to 18650 batteries with its ordinary electric soldering. However, this powerful flux is corrosive, not light to corrode the battery case and the positive electrode, and there will be corrosion on the tip.
The 18650 lithium-ion battery welding method is as follows: 1, first scratch the water welded portion first with a knife or file; It is necessary to pack the battery with a damp cloth; 4, one hand uses solder wire to the battery, one hand is welded to the solder iron for the battery to tin. 18650 Lithium Ion Battery Repair Method 1, remove your 18650 lithium ion battery, remove it, treated with temperature, the battery will greatly shorten the usage time in the case of unstable temperature, because the battery is no electricity and quite part Lithium ions have been memorized to use such methods to release the memory, in winter, put it outside for a while, then go to the house. 2, there is a method, remove the battery, put a week, will slowly consume the electricity, first use the machine to completely consume the electricity.
Then all rinters, and estimates that your current charging time is definitely very short, after full, disconnect, repeated a few times, absolutely effective. 3. In order to completely activate the 18650 lithium-ion battery, it is necessary to completely charge, discharge it several times.
The discharge circuit is composed of resistance and the light-emitting diode, and the state of discharge can be estimated by the light emitting diode. Lithium-ion battery processing welding process from the manufacture of lithium ion battery cells to battery PACK, welding is a very important manufacturing process, conductivity, strength, gas tightness, metal fatigue and corrosion resistance of lithium-ion battery, It is a typical battery welding quality evaluation standard. The battery products that do not meet such standards will be strictly prohibited to list sales, and the company is losses.
The laser is welded to a lithium ion battery as a welded heat source, and the welding workbench, precision fixture, automatic upper mechanism, and the lower body mechanism are used to form an automated welding production line. Save the cost of humanity while preventing manual misoperation, with a good product rate of more than 98%. The advantage of laser welding lithium-ion battery 1.
The laser device covers a small area, which can release a large amount of space for other flexible arrangements; 2. Laser welding without air and noise pollution, no dust, belongs to new source products, more adapt to high technology The use of a dust-free workshop; 3. The laser is low, the electro-optical conversion rate is high, the equipment loss is low, and the maintenance cost is greatly reduced, and the production cost is reduced, and the production profit of lithium-ion battery manufacturers; 4.
Laser Welding can adjust the welding speed, welding depth, welding width, etc. according to requirements, and adapt to welding of different materials and products, meet precision welding, more reliable quality, and neat appearance. The above is the introduction of 18650 lithium-ion battery welding method, lithium-ion battery processing welding process.
The lithium-ion battery has developed more hot energy storage batteries in recent years. It is still more mysterious about us, as long as we understand these difficulties in the power lithium battery welding, it is believed that it will be able to break through Difficulty of welding.
