Application of lithium batteries

The application of lithium battery packs and precautions for their use. Lithium batteries are a representative work of new energy in the 21st century, and they are also a new milestone in the industrial field. The application of lithium batteries and lithium battery packs is increasingly integrated into our lives, and we come into contact with them almost every day. Let's take a look at the precautions for using lithium battery packs.

The application of lithium battery packs is widely used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants due to their high energy, high battery voltage, wide operating temperature range, and long storage life;

The uninterruptible power supply for postal and telecommunications, as well as various fields such as electric tools, electric bicycles, electric motorcycles, electric vehicles, special equipment, and special aerospace. And with its unique performance advantages, it has been widely used in portable appliances such as laptops, cameras, and mobile communications.

With the shortage of energy and the pressure of global environmental protection, lithium battery packs are now widely used in the electric vehicle industry, especially with the emergence of lithium iron phosphate materials, which further promotes the development and application of the lithium battery industry.

The widespread application of lithium batteries in just a few years is precisely due to these excellent characteristics. Currently, almost 90% of small digital products use lithium batteries.
The most obvious change is in mobile phones. Previously, our phones used nickel cadmium batteries, but now most phones on the market use lithium batteries. Moreover, the launch of electric vehicles often becomes the headline of various battery versions. This also indicates that the application of lithium batteries and lithium battery packs in our daily lives is becoming increasingly widespread and profound.

Precautions for using lithium battery packs

1. The first thing to note about lithium battery packs is that the wires connecting the batteries must be firm and copper wires must be avoided from crossing and colliding with each other. If they cross and collide, it will cause damage to the controller of the lithium battery.
2. During the use of lithium batteries, it is necessary to have temperature control conditions. The electrode isolation material inside the lithium battery is an organic plastic product and must not be used in environments that exceed the temperature limit.
3. Lithium batteries should not be stored at full capacity for a long time, as prolonged storage can easily cause swelling and affect discharge performance. The optimal storage voltage is around 3.8V per unit, and fully charged before use can effectively prevent battery swelling.
4. Lithium battery packs cannot be short circuited for use, and there should be no direct short circuiting between the positive and negative poles of the battery. The consequence is that the explosion-proof valve will open, and in severe cases, it may burst.
5. Lithium battery packs should not be used with over discharge, and the discharge voltage should not be lower than the lower limit voltage of the battery, which will affect the battery's cycle life; It cannot be overcharged, the charging voltage should not exceed the upper limit voltage of the battery, the explosion-proof valve should be opened, and in severe cases, it may burst.
6. Different models of lithium battery products cannot be mixed for use, as there are serious safety hazards due to significant deviations in battery structure, chemical composition, and performance.
