1. Materials to be noted for battery system customization: most digital products are ternary material system cells, such as cellular phone, tablet computer, Bluetooth headset, and lithium iron phosphate system plates with high capacity polymer batteries and more uses;Ternary materials usually have a voltage of 3.7V, while lithium iron materials have a voltage of 3.2V.Polymer battery ruffled design should pay attention to the width of the different size: because these polymer battery companies generally can use single or double flanged flanging technology, battery system is placed after the folding edge will loosen, such as our original hem is 20 mm wide, due to China's battery after folding pu so would loosen some questions to about 20.3 mm, don't plan to pay at this time, it is also a test of their products as a designer, remember to keep the space information or leave a good battery development space.
2, polymer battery thickness size note: due to polymer battery itself is inflation, all soft package of battery charging and discharging swells after a certain number of times, so want to consider the thickness of the expansion ratio in the product design, in addition to using calipers force and weak card card battery thickness, thickness change, do not believe that you can find a caliper test the thickness of the polymer lithium-ion batteries, at least 10 wire thickness deviation.
3, Polymer battery capacity description: in the corresponding battery space can reach a certain capacity, but not 100% of the capacity of this battery segment, so polymer lithium battery manufacturers will customize the battery capacity of the upper and lower limits.
4, polymer lithium battery voltage control system construction should pay attention to: the high voltage and average voltage must pay attention to distinguish between students, such as high voltage of 4.35 V can be used (charge) voltage to in polymer lithium battery management system must be clear custom specifications of enterprises, and ordinary or 4.2 V voltage (charge), if you don't show the clear we'll give you a customized into 4.2 V voltage technology system, where you and Peter out, it is recommended that you have to know staff know your product development chip power supply scheme, see exactly what kind of voltage quality compared with the architecture it is 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 for 0.2C discharge;HM battery current is relatively large and is generally 10A, for example, the model aircraft with A polymer battery life is 802540-600mah 20C discharge can be used in the model aircraft, so must work when the custom battery current is A clear understanding of how to continue in the best way A, A current instantaneous work.
6, battery pole ear note: lithium-ion polymer battery should need to pay attention to improve the overall structure size batteries, especially for the positive ear size of the polymer battery, the positive pole ear particularly vulnerable, because soft package battery several times would be easy to break, turn the laser welding nickel is generally positive, ears, when use can work according to the empirical emphasized the positive bending the ear cannot have no more than 3 times, if you use the battery RongJian big enough so you can through the adoption of such wide and thick ear polymer lithium battery custom design scheme to solve the problem of the ear is easy to break.
7. Most finished batteries are equipped with protective plates, wires, plug wires, shells, etc.While some projects may require FPC soft wiring, such as iPhone batteries, some projects may require plastic cases, such as walkie-talkie batteries, which require communication protocols, such as car batteries;Therefore, these projects in the use of polymer lithium battery customization process must clearly explain all the details, involving large current, case and case color, screen printing, communication protocol, etc., the more detailed the better, the more detailed the better to reduce the error.
8, polymer battery shell should pay attention to: don't intentionally scratched surface of the battery, because the polymer lithium battery surface is very fragile, easy to scratch, and some customers in the incoming inspection when deliberately use nails cut surface of the battery, and then make a battery supplier embarrassment this kind of behavior is very shameful, we should put an end to, and will stop the bad moral behavior.
Made of polymer lithium battery if provide customized data is not complete, not only affects the production efficiency, the ability to work can also lead to bad mistake, more to the point when the larger safety problems may lead to the product, so in polymer lithium battery custom summarizes several experiences for lithium battery friend reference, whether in doing project design products or polymer battery custom reports on implementation plan will have great help.
