The advantages and disadvantages of 18650 lithium-ion battery
*Lishen LR1865HC 3500mah 3.6V 18650 lithium cylindrical battery cell
The 18650 lithium-ion batteries, the biggest drawback is he has fixed well, the volume of the packed in some notebook or when some products are not very good, this drawback, of course, also can saying is an advantage, it is relative to other polymer lithium-ion battery, and we can customize lithium-ion battery. It can change the size of this is a disadvantage. There is also an advantage for products with specific battery specifications.
18650 lithium-ion battery is prone to short circuit or explosion but also related to the polymer lithium-ion battery, if the relative general battery, this disadvantage is not so clear.
18650 lithium-ion battery processing must have a defensive line, and the alert battery is overcharged and lead to discharge. Of course, this is necessary for lithium-ion batteries, which is also a common disadvantage of lithium-ion batteries because the materials used by lithium-ion batteries are lithium cobalt acid materials, and lithium cobalt acid materials of lithium-ion batteries can not be large current discharge, poor safety.
The 18650 lithium-ion battery processing conditions are high, related to the general battery processing, 18650 lithium-ion battery processing conditions are high, which undoubtedly increases the processing cost.
1. The capacity of a large 18650 lithium-ion battery is generally 1200mah~3600mah, and the available battery capacity is only about 800mah; if combined into a 18650 lithium-ion battery pack, the 18650 lithium-ion battery pack is casual can break 5000mah.
2. long life 18650 lithium-ion battery life is very long; everyday use cycle life can reach more than 500 times, is more than twice the available battery.
3. high safety performance 18650 lithium-ion battery has high safety performance, no explosion, no combustion; Non-toxic, pollution-free, after RoHS trademark certification; All kinds of safety performance in one go, the cycle times is more than 500 times; High-temperature resistance, 65 degrees of power down the efficiency of 100%. The 18650 lithium-ion battery has a separate anode and cathode to prevent short circuits. So the chances of it short-circuiting are meager. You can add a protective plate to alert the battery to be overcharged and over released, which can also prolong the battery's service life.
The voltage of lithium-ion batteries is generally 3.6V, 3.8V and 4.2V, far higher than the 1.2V voltage of nickel-cadmium and nickel-metal hydride batteries.
5. no memory effect before charging will not have to empty the remaining power, easy to use.
6. small internal resistance: polymer cell internal resistance is smaller than the general liquid cell, domestic polymer cell internal resistance can even do 35m below, significantly reduce the battery consumption, extend the standby time of the mobile phone, can fully reach the level of international standards. This polymer lithium battery which supports a large discharge current, is the ideal choice for a remote control model, becoming the most promising product to replace nickel-metal hydride battery.
7. 18650 lithium-ion battery pack can be synthesized in series or tandem
8. the use of a wide range of notebook computers, walkie-talkies, portable DVD, instrumentation, audio equipment, model aircra
