 How Does a Lithium-Ion Battery Work?

Today different types of batteries are used in different types of devices. These battery packs provide a lot of power to meet the needs of millions of people around the world. 


You can find them on laptops, mobile phones, electric cars and many other devices and devices. This is why this technology is growing in its popularity. 


These units are lightweight, provide high energy and can be charged hundreds of times. In this article, we are going to find out how these units work.


The Basics

A battery consists of several components such as an electrolyte separator cathode anode and a pair of current collectors. The anode and cathode help store the lithium. 


On the other hand, the electrolytes are responsible for carrying positively charged ions through the separator.


The motion of the ions helps to create energetic electrons. The electric current flows to the target device which can be a computer or cell phone for help. 


The function of the separator is to limit the flow of electrons inside the battery. So this is a brief introduction to the basics of these power units.


Charge / Discharge

One of the greatest features of lithium-ion batteries is that they can be charged and recharged hundreds of times. While the battery is in use it continues to discharge. The anode of the battery releases lithium ions to the other side. As a result, electrons flow from one side to the other.


On the other hand, when you charge the device lithium ions come out of the cathode and move to the other side. Therefore this is how you can charge and recharge these batteries. 


If these batteries are charged properly they can maintain their capacity even after thousands of charges and charges.


This is good news for those who do not want to replace these units after several years. Once installed these units can be good for up to 8 years if cared for. So this is one of the biggest benefits of these products.


Power density versus energy density

Power density and energy density are two common concepts that you need to understand when it comes to lithium-ion batteries. 


The stored energy density is measured in Wh / kg. This is the total amount of energy that can be stored in the battery unit relative to mass.


On the other hand, the power density or W / kg is the amount of force generated by the unit relative to the mass. 


It works like a drain bowl. The energy density is like the size of the pool. On the other hand, the density of electricity acts like a draining pool.


In short, it was an introduction to lithium-ion batteries and their function. Hopefully, this article will help you get a deeper understanding of these battery packs. If you are looking for a good battery to power your units we recommend that you try these batteries.
