0 cell is best not to use soldering iron welding, one is not good on the tin. Second, the temperature is too high if it is hot for a long time, don't accidentally melt the diaphragm, causing a short circuit. It is recommended to spot weld on the nickel sheet.
Yes, I am using a soldering iron to directly weld the connection lead, of course, the best use is to spot weld nickel sheet connection or welding with a spot welding machine.
In this way, the solder can be welded to the lithium battery. After using the flux, solder is welded on the positive and negative electrodes of the lithium battery. The wires are welded together with the 18650 lithium battery. Lithium battery pole ear negative copper sheet, can be directly welded, the whole machine is generallyAluminum sheet, ordinary soldering iron and solder can not be welded. Generally, it is necessary to transfer the nickel sheet (spot welding machine) before welding with ordinary solder.
If you want to increase the output voltage of the battery pack, the 18650 battery can be used in series with a nickel sheet. Note: It is best to use nickel sheets for connection and weld with a spot welder. This can increase the solidity of the welding; Avoid high temperature caused by the use of electric soldering iron, which will affect the battery life. When welding, it is necessary to avoid the direct short connection of the positive and negative electrodes of the battery, otherwise it will seriously damage the battery.
Good spot welding effect, lower internal resistance, oxidation resistance, corrosion resistance, batteryThe discharge time is longer and the battery spot welding is more firm. Mainly reflected in a variety of lithium battery packs, the main spot welding leading and connecting pieces of the method is as follows: The power switch of the grand battery spot welding machine is pressed to the open position to turn on the power supply. Verify that the parameters of the battery spot welding equipment have been adjusted. Prepare materials and related tools according to the parameter setting table on the right.
Because the nickel sheet is easier to weld, the resistance value of nickel is relatively low, and the copper sheet is difficult to achieve resistance welding.
N4 material grade: N4 pure nickelGold US brand: Nickel 201 US brand: UNS N02201 German brand: 4061 N4 (Nickel 201, N02201) Pure nickel alloy Overview: N4 (Nickel 201, N02201) pure nickel alloy is a pure nickel alloy composed of trace elements such as manganese and copper and the main nickel, which has good mechanical properties and excellent resistance to many corrosive environments.
.12 mm. According to the query welding technology, lithium batteries are generally welded with pure nickel sheets, pure nickel sheets are not easy to oxidize, and nickel sheet welding contact resistance standardsIt's 0.12 millimeters. Nickel sheets are thin sheets of material made from pure nickel and are a transition metal element.
Yes. According to the information on the public Dianping network, there are two places selling nickel sheets in Shihezi City, Xinjiang, namely Huaxin New Materials Co., LTD and Xinjiang Tianye Huixiang New Materials Co., LTD. Nickel sheet is pure nickel alloy after several processes wait for the sheet, common pure nickel generally includes N4 or N6, N4 pure nickel alloy is a very low carbon content of pure commercial nickel, has been used to serve up to 1230℃ high temperature environment.
NI200 is a pure commercial nickel with excellent mechanicsPerformance and corrosion resistance, high thermal and electrical conductivity, low gas content and low steam pressure. NI200 applications: food processing equipment, salt refining equipment. Mining and Marine extraction. Equipment required for the manufacture of industrial sodium hydroxide at high temperatures above 300 ° C.
The shelf life of the nickel sheet is about one year, and the specific material is not the same as the service life.
The introduction of wireless nickel plate talk here, thank you for taking the time to read the content of this site, more information about wireless charging materials, wireless nickel plate don't forget to find oh in this site.
