How to Make Lithium Ion Battery: Before the deep knowledge of how to make lithium battery, it’s important to about lithium ion batteries and their working. Lithium-ion batteries have become so popular that everyone uses lithium-ion batteries; now, you can see that all electronic companies use these batteries in their products, like in laptops, mobile phones, cameras and many other products.
Even now, electric vehicles are also powered by lithium-ion batteries so you can guess the importance of these batteries. The lithium-ion batteries are manufactured on a large scale and in big industries.
Maybe you think it is possible to make them in your home, and then it is a complicated process because you need many gadgets you cannot own in your home.
Today we will describe how to make lithium-ion batteries; no doubt that their manufacturing process is not easy, but you have the information about the manufacturing process, so keep reading the article.
The manufacturing consists of many steps as it is not an easy process; you need many gadgets and elements that are compulsory for making these batteries. Here is the step-by-step method of the manufacturing process of lithium-ion batteries.
Step-By-Step Method
The lithium-ion battery manufacturing process is complex as you think because you need many instruments and gadgets that maybe you cannot afford in your home. But you have the information about this process and how the lithium-ion batteries are made.
PCB
This part is considered the heart of lithium-ion batteries, and we know that if the heart is not working well, the living things can lose their life. The protection circuit board PCB is an essential element of batteries; the PCB performs a lot of work like it prevents the batteries from over charging and also prevents the lithium battery chemistry from getting any danger.
But you can also overcome this problem by using an intelligent charger, which stops the charging process when the battery is ultimately charged. Like when you charge the lithium cells with 4.2 volts because in this way, your cell cannot exceed the 4.2 volts.
Cells
Many people don’t have enough information about the batteries, and they will think about the purpose of cells in the batteries, so the cells and batteries are used interchangeably. The main difference is that people cannot see the cells inside the batteries, but keep in mind that actually, cells store the charge, and that is fixed in the batteries.
The battery provides a shelter to cells and some other elements of the batteries; a lot of cells are used in a single battery that also depends on the size and shape of the batteries, like the batteries that are used for solar power and UPS system have large cells, for the mobile phones and laptops, cells are comparatively used in small sizes.
These cells are arranged in different variations according to the purpose of these batteries, and the cells are commonly available in the market that you can buy easily. It would help if you connected cells with the PCB using the different wires. But keep in mind that always connect the right cables accordingly; otherwise, you may face difficulties.
Battery Holder
Maybe you are not familiar with this name, but we all have used the battery holder in our life, and even in our childhood, the toys that hold the cells are the battery holders. But for a professional battery and to use in vehicles, laptops and many other things, we need to get a proper battery holder that can easily grip everything we have to install in the batteries.
If you want a professional battery pack, you have to contact the welding workers and ask them to make a special battery pack according to your need. The companies made the battery packs in different sizes and shapes according to orders by the manufacturers.
There are many benefits of using the battery holders you make through the welders because you can change the cells after they become useless. If you open any lithium-ion battery, you will see how these holders are made. Still, now it is challenging to open the batteries because they have permanently fixed the batteries, and you can destroy your battery if you try to open them.
Wiring The PCB And Balance Leads
Now you have to wire the PCB with the cells and other elements of the batteries, and this is a very critical step that you have to perform wisely. The best method for wiring is the European-style terminal; you need to connect the wires very carefully because, in case of any mistake, you can face difficulties.
This is the main reason why lithium-ion batteries are hard to make in your home; even if you have all the instruments, you need to have all the information and step by step guide for making the lithium-ion batteries, so don’t electrocute 16.8 volts because in this way you can get burn.
This can cause damage to your PCB or cells, so be careful in this step; for this, there are many videos available on the internet by professional battery makers, or you can also watch a demo video of a well-known company about this step.
Balance Charging
In this step, you must apply or connect the wires to make them charge, like connecting the wires with the overall battery or only with cells and making a proper port or socket to charge your batteries quickly.
You can also charge only the cells and also your entire battery, but the best is to charge the battery because, in this way, you can also control the battery charging speed. But keep in mind that for charging the cells, you need to provide the 4.2 volts individually, but for the overall battery, you need to provide 16.8 volts.
The balance chargers are also available in the market that you can use to detect and stop the charging once the charge is completed.
Activate PCB
After connecting all the wires, it is time to check whether you have wired correctly and that PCB is working fine. You have to remember that for charging the cells, the 4.2 volts are enough, and you do not need to exceed this limit.
In some cases, the PCB burns when you connect all the wires and finally check the working of the PCB, so before performing this step, you have to get the proper instructions from an experienced person.
Balance the Pack
This is not about balancing the charge because this thing makes many people confused. So you have to use the cells having the same capacity or drop the cell having a high voltage because if a single cell is dropped below 2.4 volts, then the whole battery will shut down, and your device is also going to power off; that can cause trouble for you.
Safety
This is the last step that is all about safety, and you have to keep this in your mind while performing every single step because your negligence causes enormous damage. In some cases, you have to hear that batteries start to burn automatically. That is happening because of a chemical issue inside the battery.
Also, avoid breaking the batteries in your home, because this is not good and even the fire can burn your hands and fingers.
