(A) polymer lithium-ion batteries and 18650 lithium-ion batteries are not comparable
1, polymer battery materials are more complex, 18650 lithium-ion batteries are relatively simple
Polymer and 18650 which is more complex is very worth warning that security is not absolute. High-quality 18650 cells are much safer than low-quality polymer cells, so consumers still need to be discerning, the quality of the cell to ensure the condition of the 18650 volume will be larger than the polymer, so from the portable, polymer cells will be relatively light. Polymer and 18650 which is more complex, relatively speaking, polymer battery model specifications are more, not the same battery model, the battery capacity and battery specifications are not the same, not familiar with the polymer lithium-ion battery customization method of battery demanders, polymer batteries are more complex.
2, 18650 can be assembled capacity, polymer battery capacity of a single section
18650 lithium-ion battery is relatively single, because its battery model is basically the same, only the battery capacity of the battery brand differences, not the same 18650 battery manufacturer research and development takeaway 18650 lithium cell brands are not the same, usually 2200mAh, 2400mAh, 2600mAh, 2800mAh capacity Standard. According to industry insiders, at this stage, 18650 has achieved the maximum single section capacity of 3400mAh. Mobile charger if you choose 18650 as the core, basically the above specifications and connected together, nowadays, the more famous is a few imported cells, such as sung, Hisense core, Konka core, etc., and domestic 18650 battery price is relatively more convenient than imported cells.
3, polymer and 18650 which is more complex
Polymer batteries choose a layer of aluminum-plastic film outside, and then a layer of high-temperature tape, polymer encountered the greatest security is leakage, short-circuit failure, resulting in up pack, the worst condition is the formation of combustion, the formation of fire. Therefore, compared with 18650, polymer battery cells are better in terms of safety. But burning will also bring safety accident hazards, so it is proposed to use mobile charger users, try not to place the mobile charger pillow core, bedside some of these places.
(B) the advantages of 18650 lithium battery
1、Wide range of use
Laptop computers, walkie-talkies, portable DVDs, instruments, audio equipment, models, toys, video cameras, digital cameras and other electronic devices.
2、Series connection
Can be connected in series or parallel to form 18650 lithium-ion battery pack.
3、Small internal resistance
The internal resistance of polymer cells is smaller than general liquid cells, and the internal resistance of domestic polymer cells can even be less than 35m, which greatly reduces the battery's self-consumption and extends the standby time of cell phones, and can completely reach the level of international standards. This support for large discharge current lithium polymer is the ideal choice for remote control models, becoming the most promising alternative to NiMH batteries.
4、No memory effect
No need to empty the remaining power before charging, easy to use.
5、High voltage
The voltage of 18650 Li-ion battery is generally at 3.6V, 3.8V and 4.2V, much higher than the 1.2V of NiCd and NiMH batteries.
6、High safety performance
18650 lithium-ion batteries have high safety performance, no explosion, no combustion; non-toxic, non-pollution, certified by RoHS trademark; various safety performance in one go, cycle times greater than 500 times; good high temperature resistance, discharge efficiency of 100% at 65 degrees. To prevent the short-circuit phenomenon of the battery, the positive and negative electrodes of 18650 Li-ion battery are separated. So the possibility of short circuit has been reduced to the extreme. You can add a protection plate to prevent the battery from being overcharged and overdischarged, which can also extend the service life of the battery.
7、Long service life
18650 lithium-ion battery life is long, the normal use of cycle life of up to 500 times, is more than twice the ordinary battery.
8、Large capacity
18650 lithium-ion battery capacity is generally 1200mah ~ 3600mah, while the general battery capacity is only about 800, if the combination of 18650 lithium-ion battery to become 18650 lithium-ion battery pack, that 18650 lithium-ion battery pack is casually can break through the 5000mah.
1, 18650 is more durable, the battery capacity is larger
Polymer and 18650 which is durable, it is important to see the application area, if a Bluetooth sports headset even if the 18650 battery is durable and can not be put in ah, however, the size of the case is not limited, I personally recommend using 18650, relatively speaking more durable.
2, polymer battery materials are more complex, 18650 lithium-ion batteries are relatively simple
Polymer and 18650 which is more complex is very worth warning that security is not absolute. High-quality 18650 cells are much better than poor-quality polymer cells, so consumers still need to be discerning, the quality of the cell to ensure the condition of the 18650 volume will be larger than the polymer, so from the portable, polymer cells will be relatively light. Polymer and 18650 which is more complex, relatively speaking, polymer battery model specifications are more, not the same battery model, its battery capacity and battery specifications are different, not familiar with the polymer lithium-ion battery customization method of battery demanders, polymer batteries are more complex.
