Know the advantages and disadvantages of 18650 lithium batteries

Advantages of 18650 lithium battery: 1. Large capacity. The general capacity of common batteries is basically about 800mah, while the capacity of 18650 lithium battery can meet 1200mah to 3600mah. If it is combined to form an 18650 lithium battery pack, then its capacity It can exceed 5000mah. 2. Long service life. Everyone said that the 18650 lithium battery can be recharged 1,000 times, then it can be used normally for more than 500 times, which is more than twice the service life of ordinary batteries. 3. High safety performance. The safety performance of 18650 lithium battery is also very high. It is not only ecological and environmentally friendly, but also non-toxic, and can be used with confidence. It will not burn or explode like fake and inferior batteries, and its high temperature resistance is very good. . 4. The voltage of 18650 lithium battery is higher than that of other batteries, and there is no memory effect, so don't charge it after emptying it. It is very convenient to charge and use. 5. The internal resistance of the 18650 lithium battery is very small, so the self-consumption of the battery is greatly reduced, so everyone's mobile phone can extend the standby time, the level is very high, and it can be in line with the international level. Disadvantages of the 18650 lithium battery The first disadvantage: the size and size of the 18650 lithium battery is fixed. The biggest disadvantage of the 18650 lithium battery is that its volume has already been fixed. It is not very good positioning when installed in some laptops or some products. Of course, this shortcoming It can also be said to be an advantage, which is a disadvantage in terms of the customizable and changeable size of other lithium batteries such as polymer lithium batteries. And for some products with specified battery specifications, it has become an advantage. The second disadvantage: Compared with polymer batteries, it is not safe enough. 18650 lithium batteries are more prone to short-circuit or explosion. It is also related to polymer lithium batteries. If relatively ordinary batteries, this shortcoming is not so obvious. Disclaimer: The articles published on this website are all from the Internet.
