A Brief Introduction to How Lithium-Ion Batteries Work
An unusually rapid increase in Earth’s average surface temperature has been noticed over the past century. This is primarily due to the excessive release of greenhouse gases into the atmosphere caused by burning fossil fuels. To deal with this situation, we must switch to renewable sources of energy such as solar and wind.
But the sun doesn’t shine at night, and the wind doesn’t blow all the time. That is why we must store energy efficiently using batteries. Lithium batteries are the top choice when it comes to optimal performance and effectiveness. This article will focus on how lithium-ion batteries work and what are the advantages of using them.
What is a Lithium-Ion Battery?
A lithium-ion battery is a rechargeable battery that charges and discharges by the movement of lithium ions between negative and positive electrodes. Since lithium-ion batteries have a high storage capacity, they are used in a range of applications such as smartphones, PCs, production equipment and automobiles.
Compared to traditional batteries, lithium-ion batteries are lighter and offer faster charging. Moreover, they are environment friendly as they do not contain any harmful substances. Li-ion batteries can be recharged hundreds of times and still perform efficiently. All these features make for high power efficiency as lithium-ion cells have a higher charge retention capacity than other types of batteries.
Using lithium-ion batteries to power different devices can help decarbonize the environment in an efficient way. Now that we understand lithium-ion batteries, let us dive into how lithium-ion batteries work.
How Lithium-Ion Batteries Work?
Lithium-ion batteries are generally composed of the anode and the cathode, a separator between the electrodes, and an electrolyte that fills the remaining space of the battery. The lithium-ions travel between the electrodes through the electrolyte.
When a lithium-ion battery is charging up, the positive electrode releases some lithium ions, which move through the electrolyte to the negative electrode and remain there. During this process, the battery takes in and stores energy. When the battery is discharging, the lithium-ions move back to the positive electrode, producing energy that essentially powers the battery.
In both cases, the electrons flow in the direction opposite to the ions around the circuit. Note that electrons do not flow through the electrolyte. The ions move through the electrolyte, while the electrons go around the external circuit in the opposite direction. These two processes are interconnected. If ions stop going through the electrolyte because the battery is discharged, electrons can’t move through the circuit either.
Unlike traditional batteries, lithium-ion batteries contain built-in electronic controllers that help regulate how batteries charge and discharge. These also help overcome overheating and overcharging issues.
Advantages of Using Lithium Batteries
After discussing how lithium batteries work, let us talk about the advantages of using these batteries. Here are some of the key advantages of using a lithium-ion battery: -
One of the most significant benefits of using lithium-ion batteries is their portability. You can carry them anywhere you need without thinking about the overflow of acid from the battery.
- Fast Charging
Lithium-ion batteries can charge and recharge much faster than traditional batteries. It is evident from the fact that mobile batteries charge in a short time and give a full-day’s back-up.
- No Maintenance
You do not need to perform any maintenance tasks to ensure its functioning. Other types of batteries, such as nickel-cadmium, require discharge to avoid the memory effect. Lithium-ion batteries have no memory effect, which means they do not have to be fully discharged before recharging again.
- High Efficiency
Since we have discussed how lithium-ion batteries work, we are aware that they are reliable and last long. They have a high energy density, which enables their usage in devices with high power requirements, such as mobile phones and laptops.
- Charge Cycle
A lithium-ion battery has more lifespan than a traditional battery. Another advantage of lithium-ion batteries is that they are small and lightweight.
In this article, we have discussed how lithium-ion batteries work and what are their advantages. At this point, you should be able to comprehend the importance of these batteries. Compared to the other types of batteries, lithium-ion batteries last longer, charge faster and have a higher energy density. What more could you want from a battery?
