18650 lithium battery pack capacity and advantages analysis

Most applications have different current and time requirements, so most power supply batteries are presented in lithium-ion battery packs, in the selection of battery packs should be considered to choose the consistency of the cell, stability, safety, these indicators are very important. It is worth noting that many buyers have a misconception that high capacity, the actual discharge current will be large, but this is just the opposite: 18650 lithium-ion battery pack is generally divided into capacity and multiplier type, capacity type important to reflect the large capacity, but the discharge current is generally less than 1C, the current is small; multiplier type can be high current discharge, but the capacity is lower, the use of time is not long. This is similar to the fish and bear’s paw can not be both.

Now on the market in bulk to buy high-capacity 18650 lithium-ion battery pack is 2950mAh, this capacity battery is also known as 3000mAh. 2200mAh-2600mAh capacity range is more stable, the technology is more mature in all aspects.

18650 lithium-ion battery capacity will bring the negative use of high prices, so the capacity and price balance is very important. 18650 lithium-ion battery price is proportional to the size of the capacity, the larger the capacity, the greater the energy ratio, the more raw materials used, so the price will be more expensive, the general price is 10 ~ 30 yuan / piece.

18650 lithium-ion battery pack capacity is an important selling point for manufacturers, in addition, the same capacity of 18650 lithium-ion battery cell brand is also a factor affecting the price, generally speaking, imported brands than the same type of domestic brands at a higher price, as mentioned earlier, the important factors determining the capacity of 18650 lithium-ion batteries and raw material structure, and thus from the cathode, using lithium cobaltate, lithium manganate and ternary materials Lithium iron phosphate, lithium iron phosphate prices will vary.

Because the capacity of the price of the dominant use, the market 18650 lithium-ion battery capacity will be false labeling phenomenon, for example, the capacity of the capacity of 2200mAh 18650 lithium-ion battery capacity labeled 2600mAh, which is deceptive behavior of consumers, capacity does not meet the standard often caused by artificial nutrients so, users should recognize the authentic manufacturers of the brand.

18650 lithium-ion battery capacity is up to standard not only affect the user experience, in the long run, the manufacturer is also a test, consumers buy batteries, there is no need to dwell on the original foreign battery, because the domestic packaging factory will also use imported lithium-ion battery pack, its 18650 lithium-ion battery capacity is not different, the important thing is that these 18650 lithium-ion battery capacity is real.

Advantages of 18650 lithium-ion battery pack

1. بڑی صلاحیت

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 batteries to become 18650 lithium-ion battery pack, the 18650 lithium-ion battery pack is casually can break through 5000mah.

2. لمبی عمر

The service life of 18650 lithium-ion battery pack is very long, the cycle life can reach more than 500 times in normal use, which is more than twice as long as ordinary batteries.

3. اعلی حفاظت کی کارکردگی

18650 lithium-ion battery safety performance, non-explosive, non-combustion; non-toxic, non-polluting, after the RoHS trademark certification; a variety of safety performance in one go, the number of cycles is greater than 500 times; high temperature resistance performance, 65 degrees under the conditions of discharge efficiency of 100%. To prevent the short-circuit phenomenon of the battery, the positive and negative electrodes of 18650 lithium-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 also extends the service life of the battery.

4. ہائی وولٹیج

18650 lithium-ion battery voltage is generally at 3.6V, 3.8V and 4.2V, much higher than the 1.2V voltage of NiCd and NiMH batteries.

18650 power lithium-ion battery is mainly positive and negative material particles than the ordinary 18650 lithium-ion battery is more fine energy density is not large, the use of diaphragm materials and electrolyte conductivity better, better conductivity.
