The advantages of 18650 lithium battery
1. Large capacity. The capacity of 18650 lithium battery is generally between 1200mah~3600mah, and the general battery capacity is only about 800, if the 18650 lithium battery is combined into 18650 lithium battery pack, the 18650 lithium battery pack can easily break through 5000mah.
2. Long life. The service life of 18650 lithium battery is very long, and the cycle life of normal use can reach more than 500 times, which is more than twice that of ordinary batteries.
3. High safety performance. 18650 lithium battery high safety performance, no explosion, no combustion; Non-toxic, pollution-free, through RoHS trademark certification; All kinds of safety performance in one go, the number of cycles is more than 500 times; Good high temperature resistance, 65 degrees of power down efficiency of 100%. In order to prevent short circuit of the battery, the positive and negative electrodes of the 18650 lithium battery are separated. So the possibility of a short circuit has been reduced to the extreme. You can install a protection plate to avoid overcharging and overdischarging the battery, which can also extend the service life of the battery.
18650 lithium battery capacity?
18650 lithium battery capacity is the concern of many industrial users and consumers, this is because the larger the 18650 lithium battery capacity, the longer the use time, can provide users with longer power supply, but in the same system, 18650 lithium battery capacity will bring high price of the negative effect, so the balance of capacity and price is very important.
The capacity of 18650 lithium battery is distributed between 1000mAh and 3000mAh, but the technology is generally mature between 1800mAh and 2600mAh, because the capacity of 18650 lithium battery is too low, which will affect the effective working time of the battery, and there are problems in applicability. The 18650 lithium battery capacity is too high, the cost rise is larger, and the significance of non-special areas of high-capacity 18650 lithium batteries is not very large.
18650 lithium battery capacity is the main selling point of manufacturers, in addition, the same capacity of 18650 lithium battery cell brand is also a factor affecting the price, in general, imported brands than the same type of domestic brand price is higher, said before, the main factor determining 18650 lithium battery capacity and raw material structure, so from the positive point of view, The price of lithium cobaltate, lithium manganate and ternary materials, lithium iron phosphate will be different.
18650 lithium battery pack needs to be customized according to different products used in different working environments and fields, in the selection of 18650 lithium battery pack should consider the consistency, stability, safety of the battery cell, and each battery in each group of cells, all aspects of the value should be paired, such as the same voltage, the same internal resistance, the same capacity and so on.
