What to pay attention to when customizing polymer lithium batteries

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. 2. Pay attention to the different size design of the folding width of the polymer battery: because these polymer battery companies generally can use single or double folding technology, the battery edge will loosen a little when the battery system after the folding is placed, such as ours The original folding edge is 20mm wide. After folding, due to the battery Pu of our country, some problems 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. 3. Pay attention to the thickness and size 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. The thickness will change with Wuli card. I don’t believe you can find a polymer lithium battery with a caliper to detect the thickness. There is at least 10 threads of thickness deviation. 4. Polymer battery capacity description: It can reach a certain amount in the corresponding battery space. 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, you can take it away without biting the bullet. Pay attention to the polymer battery output: generally small polymer battery output lines are mostly, and the output end of the battery terminal cable is related to the terminal type, such as JST terminal, PH terminal, terminal 1.25 part, 2.0 terminal, 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 power supply and plug socket input circuit 34 to other, Or to ensure basically face-to-face communication, for example, lithium polymer batteries can be customized and formed error-free. 6. 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) voltage management system must be customized in polymer lithium battery The manual stated that the company is clear, and the general one is 4.2V voltage (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 employees are aware of your product development chip power supply service methods, and see what voltage quality system structure is more appropriate. 7. Pay attention to the working current of the battery: For example, some Bluetooth headset batteries have relatively small working current, which is generally sufficient for 0.2C discharge; HM battery current is relatively large and generally 10A, for example, a model aircraft with polymer battery life is 802540-600mAh 20C discharge It can be used in model airplanes, so it is necessary to customize the battery current when working is a clear understanding of how to continue the current of A and A in the best way to work instantaneously. 8. Pay attention to the 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 tabs. 9. 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 casings, 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. 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. 10. Pay attention to the shell of the finished polymer battery: 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.
