There are many lithium batteries we use, and 18650 lithium batteries are one of them. The most common use of 18650 lithium batteries is as a battery for laptops and a 18650 vacuum cleaner lithium ion battery. In addition, we say that the 18650 lithium battery is the originator of the lithium battery, and it is the standard of the battery model, which is very cost effective. Common lithium-ion batteries and lithium iron phosphate batteries are all 18650 lithium batteries. The advantages of 18650 lithium batteries are light weight, large capacity, and no memory effect. Let's take a look at 18650 lithium batteries from various aspects.
Our common 18650 lithium battery has 3.7V and 4.2V. Although the standard is different, their performance is the same, which is due to the different labeling of the manufacturer. Generally, the 3.7V of the 3.7V 18650 lithium battery refers to the typical voltage, which is the discharge voltage during use. The 4.2V of the 4.2V 18650 lithium battery is the voltage when the battery is fully charged, so the battery we see is marked. Whether it is 3.7V or 4.2V is ok, it has no effect on our use.
In theory, the 18650 lithium battery can be recharged a thousand times, which is its life, so the battery of the notebook we use generally chooses 18650 lithium battery as the battery. The 18650 lithium battery has the advantage of excellent stability, so it is very stable in use at work. Today, 18650 lithium batteries are widely used in various electronic fields. Examples include mobile power, medical and industrial instruments, various portable devices, and wireless data transmitters. The 18650 lithium battery is the first choice for most IT industries. Because the IT industry uses very high computer configuration requirements and the stability requirements are very high, most computers used in the IT industry choose to use 18650 lithium batteries as the energy source.
The 18650 lithium battery is widely used in various electronic fields because of its many advantages, such as the following:
1. The capacity is large
our common battery capacity is about 800mah, and the capacity of 18650 lithium battery can reach 1200mah to 3600mah, if combined to become a 18650 lithium battery pack, then its capacity can exceed 5000mah.
we said earlier that 18650 lithium battery can be recharged a thousand times, then it can be used more than five hundred times, more than twice the life of ordinary batteries.
It is environmentally friendly, pollution-free, and non-toxic, and can be used at ease, will not be like inferior battery burning or explosion, and its high temperature performance is very good.
4. No memory effect
18650 lithium battery voltage is higher than other batteries, there is no memory effect, so do not have to charge the battery and then recharge, with the charge, very convenient.
5. Small internal resistance
18650 lithium battery internal resistance is very small, so the battery's self-consumption power is greatly reduced, so our mobile phone can extend the standby time, the level is very high, can be in line with international standards.
Based on the above information about these 18650 lithium batteries, we know that the 18650 lithium battery is different from other lithium batteries in terms of type difference, use and advantages. It is because of its advantages that the 18650 lithium battery has been used in a wide range of applications. Most of the notebook computers, various electronic products, various industrial and medical instruments use 18650 lithium batteries, and the raw materials of 18650 lithium batteries do not have to rely on foreign imports, so they are cheap and easy to use. If there is demand, it must be Find a professional manufacturer to customize.
