18650 lithium battery and polymer lithium battery which is better and more durable?

Many people are asking which is better, 18650 or polymer, and which is durable, polymer or 18650. As long as the comprehensive test and comparison analysis of the performance of Li-polymer and 18650 Li-ion batteries, you can understand which is safe, 18650 or polymer. Only after testing the 18650 and polymer battery performance, you will find these details related to polymer and 18650 which is better, these will have test data in the special battery performance and safety test room for lithium battery manufacturers.

A, polymer and 18650 which is durable?

1, polymer and 18650 which is durable first from the shape, 18650 lithium battery belongs to the cylindrical, while the polymer battery is shaped or square, polymer battery external aluminum plastic film packaging, the external is relatively fragile easy to scratch, dent, broken skin, if you accidentally drop the polymer battery to the ground, the battery positive ear is easy to break. While the cylindrical battery 18650 shell using metal shell, even if dropped a few times will not have a major problem.

2, polymer and 18650 battery if the same ternary materials, the polymer and 18650 battery storage conditions, polymer and 18650 battery charging and discharging conditions, 18650 and polymer battery conditions of use, 18650 and polymer cycle conditions are the same, the same standard voltage standard structure and the same working environment, in fact, basically can not be distinguished 18650 and polymer batteries that durable.

3, polymer and 18650 which durable, mainly depends on the application scenario, if a Bluetooth headset even if the 18650 battery is durable and can not be put in ah, but the size of the case is not limited, it is recommended to use 18650, relatively speaking more durable.

Second, polymer and 18650 which price is expensive?

1, polymer and 18650 price which expensive mobile power with 5000mAh cells to calculate, 18650 at least need two 2600 parallel to reach 5000MAH, while the polymer to do 5000MAH can be in the size range of casual changes. According to the shape you need to make out; but 18650 at present only Panasonic Sanyo's single maximum can do 3200MAH, you can buy 5000MAH polymer cells.

2, the same comparison price polymer is much more expensive, such as domestic: 5000MAH polymer price at 35 yuan, 18650 also two parallel price at 27 yuan, but 18650 than the polymer cells are more dangerous to explode, my advice to choose polymer cells, safety first.

Third, 18650 and polymer battery which is safe?

1, 18650 and polymer which safety first of all to understand their battery structure design, if 18650 lithium batteries and lithium polymer batteries in the structure design above are no problem, it is necessary to find the reason for the charger, normal to see the 18650 and polymer battery specifications on the requirements of the charging current settings, overcharging is easy to battery safety problems.

2, 18650 and polymer which safety also depends on the consumer, the correct use of lithium batteries to ensure battery safety, of course, consumers also have the obligation to use the correct battery, which is related to 18650 and polymer safety issues, but there are no absolutes, Apple cell phone lithium battery global brands have also been lithium battery failure problems, South Korea's Samsung cell phone lithium battery equivalent safety problems caused by the company's market value evaporated more than N100 million. Market value evaporated more than N billion.

3, 18650 and polymer which is relatively safe, polymer battery improper use is easy to drum combustion, and 18650 lithium battery improper use is easy to explode, which means that as long as the battery is not used correctly may have security risks.

Fourth, 18650 and polymer which is better?

1, 18650 lithium batteries and polymer batteries which is really not a good conclusion, but if not used properly, then the good battery is also easy to bad, but in terms of battery structure, 18650 batteries are easier to design and assemble some, and the market are public mold supporting materials, relatively low cost; and polymer batteries in the structure is more complex, in addition to consider the normal electrical performance safety, but also consider In addition to the normal electrical safety, we must also consider the appearance of the PACK assembly, the easy fracture of the positive lug during PACK processing, etc.

2, 18650 and polymer which is good from the consumer point of view, may prefer polymer batteries, after all, it is the chance of burning to a small rate 18650 batteries, while 18650 misuse will have the risk of combustion and explosion, so sometimes perhaps in front of 18650 and polymer which is good, more people choose polymer it.

Five, polymer and 18650 which complex?

1, polymer and 18650 which complex, relatively speaking, polymer battery models are more, different battery models, their battery capacity and battery size are different, not familiar with the polymer lithium battery customization program for the battery needs, polymer batteries are much more complex.

2, polymer and 18650 which complex, while 18650 lithium battery is relatively single, because its battery model is the same, only the battery capacity of the battery brand is different, different 18650 battery manufacturers R & D takeaway 18650 lithium cell brands are different, generally have 2200mAh, 2400mAh, 2600mAh, 2800mAh capacity Standard. According to industry insiders, 18650 has achieved the maximum single section capacity of 3400mAh. If the mobile power is using 18650 as the core, basically the above specifications and connected together, now more famous is a few imported cells, such as Samsung cells, LG cells, Panasonic cells, etc., and domestic 18650 battery price is relatively more convenient than imported cells.

3, polymer and 18650 which complex: polymer battery outside the use of a layer of aluminum plastic film, outside and then wrapped in a layer of high-temperature tape, polymer found that the greatest security is leakage, short circuit, resulting in the package, the worst case is to produce combustion, producing fire. Therefore, compared with 18650, polymer battery cells are better in terms of safety. But burning will also bring security risks, so it is recommended that the use of mobile power users, try not to place the mobile power pillow, bed these places.

4, polymer and 18650 which complex is worth reminding that security is not absolute. Quality 18650 cells than poor quality polymer cell security is much better, so the masses still need to shine a bright eye to identify, the case of quality assurance of the core, 18650 volume will be larger than the polymer, so from the portability, polymer cells will be more lightweight.
