10 factors for customizing polymer lithium batteries

1. The factor of the width of the folded edge of the polymer battery: Because the polymer battery generally adopts single or double edge folding technology, the edge of the battery will loosen a little when the battery is placed after the edge is folded. For example, the original edge is 20mm wide. Behind the side because the battery will loosen up to about 20.3mm, don't count it at this time, this is also when testing the product designer, remember to leave more space or leave a good battery space. Double folding edge of polymer battery 2. Thickness and dimension factor of finished polymer battery: Because polymer battery itself is swelling, all soft pack batteries will expand after a certain number of charging and discharging, so the expansion rate of thickness should be considered when designing the product. , In addition, when using the caliper card battery thickness, the thickness will vary. If you don’t believe it, you can find a polymer lithium battery with a caliper to test the thickness. There will be at least 10 wire thickness deviations. Thickness test 3. Battery material system factors: Most digital products use ternary battery material systems, such as mobile phones, tablet computers, Bluetooth headsets, etc., while the high-capacity polymer batteries used in cars use lithium iron phosphate systems. Many; the normal voltage of ternary material is 3.7V, while the voltage of iron-lithium material is 3.2V. 4. Polymer battery capacity factor: A certain capacity can be achieved in the corresponding battery space, but it is not 100% of this battery capacity segment, so the polymer lithium battery custom manufacturer will give the upper limit and the upper limit of the battery capacity. Lower limit; for example, the design capacity given by the manufacturer during the evaluation is 100mAh, but 95mAh will appear during the actual processing. These are all normal, because the design will have positive and negative tolerances. A polymer lithium battery parameter design 5. Polymer lithium battery voltage system factors: high voltage and ordinary voltage must be distinguished, such as high voltage 4.35V (when fully charged) voltage system must be customized in polymer lithium battery It is clearly stated in the instruction manual, and the ordinary voltage is 4.2V (when fully charged). If you do not explain clearly, we will customize the 4.2V voltage system for you, and you are there again. It is recommended that you know clearly about you. The power supply method of the product chip depends on which voltage system is more appropriate. 6. Battery working current rate factor: For example, some Bluetooth headset batteries have relatively small working current, generally 0.2C discharge is sufficient; while the working current of aeromodelling battery is relatively large, generally about 10A, such as a polymer used for aeromodelling The 802540-600mAh battery can only be used on the model airplane when it is discharged at 20C. Therefore, when customizing the battery, you must know the working current. It is best to last how many A and how many A current it works instantly. An aeromodelling battery 8025407, battery lug factors: when polymer lithium batteries, you should pay attention to the overall size of the battery, especially the size of the positive lug of the polymer battery, because the positive lug of the soft pack battery is particularly fragile, and it is easy to break after a few folds. It is laser welding of positive lug to nickel. According to relevant experience, it is emphasized that the number of bending of the positive lug should not exceed 3 times during use. If the battery capacity is large enough, the custom method of polymer lithium battery with thick and wide lugs can be used to solve the easy fracture of the lugs. The problem. Do not bend the positive ear of the polymer battery easily. 8. The output factor of the polymer battery: Generally, the output of small polymer battery is mostly the wire, and some of it is the output battery terminal wire, which involves the corresponding model of the terminal, such as JST Terminal, PH terminal, 1.25 terminal, 2.0 terminal, 2.54 terminal, 3.96 terminal and so on. In addition, the terminals are also divided into forward and reverse directions. If they are connected in the wrong direction, the product will not work or even burn the product. If you don’t know, you can Supply the plug socket and battery-powered input circuit to the other party, or communicate face-to-face. This basically ensures that the customization of the polymer lithium battery can be formed at one time and there is no error. A custom-designed polymer lithium battery product drawing 9. Factors for the finished product of the battery PACK: Most of the finished PACK battery is equipped with protective plates, wires, plug wires, shells, etc., and some special ones may be added with FPC flexible cables, such as For Apple mobile phone batteries, some need to be added with plastic shells, such as walkie-talkie batteries; some need to be added with communication protocols, such as car batteries; so these items must be customized with polymer lithium batteries for all detailed information. The expression is clear, and the more detailed the better, the more detailed the better, the more detailed it can reduce the mistakes. Polymer battery soft pack protection customization method 10. Factors of the finished polymer battery shell: Do not deliberately scratch the surface of the battery cell, because the surface of the polymer lithium battery is very fragile, and it is easy to be scratched if you are not careful, and the quality of some customers is When inspecting incoming materials, it will deliberately scratch the surface of the battery cell with your fingernails, and then make things difficult for the battery supplier. This behavior is very shameful. We should put an end to, oppose, and stop this kind of bad moral behavior. do you accept? Disclaimer: The articles published on this website are all from the Internet.
