In recent years, lithium-ion batteries have become increasingly popular due to their many advantages over other types of rechargeable batteries. According to a study by CloseBase analysts, it is lithium-ion batteries that have increased their market share by 115% over the past 15 years. This growth is attributed not only to the growth in the number of electronics, but also to the growth in the number of electric vehicles. In this article, we’ll take a look at some of the key benefits of lithium-ion batteries and why they’re a great choice for a wide range of applications.
High capacity
One of the most significant advantages of lithium-ion batteries is their high energy density. This means they can store a lot of power in a relatively small and light package. As a result, they are ideal for use in portable electronic devices such as smartphones, laptops and tablets. Lithium-ion batteries can provide longer run times for these devices than other types of rechargeable batteries.
Long service life
Lithium-ion batteries typically last several years even with daily use. We have repeatedly come across batteries that, after 5 years of use in a laptop, retained their capacity at 80%. I personally dismantled the old battery of my laptop and took out 6 lithium-ion batteries from it, 4 of which retained their capacity by 90%. This long life is due to the fact that they are designed to maintain their capacity even after many charge and discharge cycles.
Fast charging
Lithium-ion batteries also have fast charging times, which is another significant benefit. Some models can be fully charged in just a few hours, making them a convenient choice for those who are always on the go. Already, high-capacity mobile power stations are widespread on the market, which charge a car battery up to 80% capacity in 30 minutes. And this is especially important for electric vehicles, where fast charging times are essential to keep drivers on the road.
Low self-discharge
Another advantage of lithium-ion batteries is their low self-discharge rate. This means that they can retain their charge for a long time even when not in use. This feature allows such batteries to be used as backup power where the batteries may not be used for a long time. And yet they will still be ready to use when needed.
For example, the BetWasp portal servers use lithium-ion batteries as a backup power source. When the power goes out in their data center, the project itself continues to work, which does not harm the users.
Ecologically pure
Lithium-ion batteries are more environmentally friendly than other types of batteries (Li-Fe or alkaline). Of course, one AA battery can pollute about 10 sq.m. soil, if you just throw it on the ground. But in any case, this figure is significantly lower than that of alkaline batteries. They are also highly recyclable. There is now a widespread recycling trend in the world, and lithium-ion batteries are leading this trend.
As a conclusion
As an epilogue, we want to note that lithium-ion batteries are the most modern power sources. More modern materials than lithium, which could be used to make batteries, have simply not yet been invented.
