Today an 18650 battery is used in a variety of electronic devices such as DSL cameras. What makes these drives so popular are three main features: long lifespan, high power density, and low cost. In these three areas, these units offer the best performance. The description of these three advantages of these units is presented below. Keep reading to know more.
1) cost factor
When it comes to cost, you may need to spend a little more money to buy a lithium-ion battery pack. But if you compare the operating cost of these units with that of their counterparts, you will be surprised to learn that the cost is three times less.
For example, gasoline cars cost three times more than electric cars. The high capital cost is due to the inclusion of cobalt and nickel in the metal oxide mix. Therefore, these units cost up to 6 times more than the usual lead-acid units.
2) Energy density
The energy density of an 18650 lithium-ion battery pack is much higher than other technologies. The energy density is affected by the storage medium. Currently, the researchers are looking for a way to change the storage medium to silicon.
In this case, the energy density will increase about 4 times. A big disadvantage of silicon is that it can trigger a lot of contraction and expansion during each cycle. Therefore, only 5% silicon is used in combination with graphite.
3) Longevity
Longevity is another great advantage of these units. Your old laptop’s battery won’t last more than a year. However, batteries in today’s laptops can last up to three years or more. This is what makes these drives so popular with a lot of users and manufacturers.
Testing method
The testing phase of these battery packs can help determine the capacity of the cells so that you can form a pack. If you want to test, all you need to do is get a voltmeter, four trays, and an RC charger. You can use your voltmeter to test the cells and get rid of the ones that read below 2.5.
You can use the intel charger to connect the cells. It will charge them at a rate of 375 milliamps/hour. In this case, if you connect two cells, each will get 750. Now, you can mention the capacity of each unit. Then you can group them based on capacity parameter to use in different batteries.
These days, almost all types of major devices use lithium-ion batteries as their primary source of power. There is only a small change in the composition of the chemical. Depending on the density and energy use, the life cycle of these units can be different.
In short, these are just some of the main advantages of this type of battery. Hopefully, you will find this article useful enough to better understand this technology.
