How to customize polymer lithium battery

1. Materials to pay attention to in battery system customization: Most digital products are ternary material system cells, such as cellular phones, tablet computers, Bluetooth headsets, and lithium iron phosphate system boards with high-capacity polymer batteries; Ternary materials usually have a voltage of 3.7V, while at 3.2V it is a lithium iron material. Please pay attention to the different size design of the folding width of the polymer battery: because these polymer battery companies generally can use single folding or double folding technology, the edge of the battery will loosen a little when the battery system is placed after the folding, such as our original folding The side is 20mm wide. After folding, some problems will be loosened due to the battery Pu of our country, and the problem will be about 20.3mm. Don't count it at this time. This is also a test of your product as a designer. Remember to leave more space information. Or leave room for battery development. 2. Pay attention to the thickness of the finished polymer battery: Because the polymer battery itself swells, all soft pack batteries will swell after a certain number of charging and discharging. Therefore, the expansion rate of the thickness should be considered in the product design, except for the use of calipers to check the thickness of the battery. And Wulika, the thickness will change, I don’t believe you can find a polymer lithium battery with a caliper to detect the thickness, at least 10 wires thickness deviation. 3. Polymer battery capacity description: in the corresponding battery space can reach a certain level The capacity, but not 100%, is the capacity segment of this battery, so the polymer lithium battery manufacturer will customize the upper and lower limits of the battery capacity; for example, the manufacturer’s evaluation of the design capacity is 100 mA, and the actual processing technology will be 95 Milliampere, these are normal, because the design will have positive and negative deviations, and it can be taken away without biting the bullet. As shown in Figure 5, the polymer battery output is to pay attention: generally small polymer battery output lines are mostly, but also the output terminal of the battery terminal cable, which relates to the terminal type, such as JST terminal, PH terminal, terminal 1.25 The part, 2.0 terminals, terminals 2.54, 3.96 and such terminals, other terminals also indicate forward and backward. If the direction is wrong, the product may not work properly, or even the product will burn. If you don’t know it will be battery powered and plug sockets. Input circuit 34 to other, or to ensure basically face-to-face communication, such as lithium polymer batteries can be customized and formed error-free. 4. Pay attention to the construction of polymer lithium battery voltage control system: high voltage and general voltage must pay attention to the distinction between students, for example, high voltage 4.35V (when overflowing electricity) voltage management system must be customized in polymer lithium battery The manual stated that the company is clear, and the general voltage is 4.2V (when overflowing). If you don’t explain clearly, we will customize the 4.2V voltage technology system for you, and you are there again. I suggest you It is necessary to know that the employees know your product development chip power supply service method, and see what voltage quality system structure is more appropriate. 5. Pay attention to the working current of the battery: For example, the working current of some Bluetooth headset batteries is relatively small, generally enough to discharge at 0.2C; the current of HM battery is relatively large, generally 10A, for example, the model aircraft with polymer battery life is 802540-600mAh 20C discharge It can be used in model airplanes, so it is a clear idea to customize the battery current when working. It is a clear understanding of how to continue the current of A and A in the best way. 6. Pay attention to battery tabs: When polymer lithium batteries, you should pay attention to increasing the overall structure size of the battery, especially the size of the positive tab of the polymer material battery, because the positive tabs of the soft-pack battery are particularly fragile, and it is easy to fold it several times. Usually the positive ear is laser welded to nickel. When using it, it can be emphasized that the number of bending of the positive ear can not exceed 3 times according to work-related empiricalism. If the battery capacity is large enough, it can be polymerized by using thick and wide tabs. Custom-designed methods of lithium batteries to deal with the problem of easy breakage of the tabs. 7. Attention should be paid to the finished battery pack: most finished batteries are equipped with protective plates, wires, plug wires, shells, etc. Although some projects may require FPC flexible wiring, such as Apple mobile phone batteries, some projects may require plastic shells, such as walkie-talkie batteries, communication protocols, such as car batteries; therefore, these items must be clearly stated in the process of using polymer lithium batteries to customize All the details, involving high current, shell and shell color, screen printing, communication protocol, etc., the more specific the better, and the more specific the better it can reduce errors. 8. Pay attention to the finished polymer battery shell: Do not intentionally scratch the surface of the battery, because the surface of the polymer lithium battery is very fragile, and it is easy to scratch accidentally, and some customers will deliberately scratch the surface of the battery with their nails during the purchase inspection. It is very shameful to embarrass battery suppliers. We should put an end to, oppose, and stop this bad ethical behavior. When ordering polymer lithium batteries, if the supply of customized data is incomplete, it will not only affect the processing efficiency, but also cause The misunderstanding of poor work ability may lead to greater safety issues in the product when it is more critical. Therefore, for the customization of polymer lithium batteries, a few practical experiences are summarized for the reference of lithium battery friends, whether they are doing engineering project design products. Or it will be helpful when reporting on custom-made implementation methods for polymer batteries. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
