Lithium batteries are very famous these days because they are used for many purposes, like in electronics and automobiles. Technology is working so fast that new things are introduced and invented daily. Like this, lithium batteries are available in different types, but here we only discuss the two main types, including the lithium-ion and polymer batteries.
Many people think they are the same batteries and have the same functions, but that is now true because they are different and used for other purposes; some things are in both every day, but many properties are different. Read a complete difference between lithium-ion battery vs lithium-polymer battery and know which one is best for you.
What Is a Lithium-Ion Battery?
Lithium-ion batteries can be used most of the time, and now all the electronic brands prefer to use lithium-ion batteries in their gadgets because they are less costly, long-lasting and have energy density compared to the other batteries.
The lithium-ion batteries are rechargeable, which is why they are considered highly portable batteries, and that’s why they are primarily used in electronics, like aerospace gadgets.
In lithium-ion batteries, the positive lithium ions move from anode to cathode and vice versa through the electrolyte. These batteries are highly durable and last 3 to 4 years easily without falling or more.
A significant main thing that distinguishes the lithium-ion battery from lithium polymer is an electrolyte because, in the lithium-ion battery, the electrolyte is a liquid.
What is Lithium Polymer?
This is another rechargeable battery that uses the polymer as an electrolyte instead of any liquid like in the lithium-ion battery. This property makes the lithium-ion batteries safe to use and more efficient because there is no need to worry about any explosion that unfortunately happens in the lithium-ion batteries.
Lithium polymer batteries are available in different sizes and shapes as they are versatile; they are also very lightweight, like lithium-ion batteries.
What Is The Difference Between Lithium-Ion Battery VS Lithium-Polymer Battery?
Both of these rechargeable batteries, the lithium-ion battery, became very popular after 1980, and then most electronic companies preferred to use the lithium-ion batteries. A lithium-ion battery consists of three major things: the positive electrode, a negative electrode, and a liquid electrolyte called the liquid chemical compound, which works as a medium of connection between them.
But now, these batteries also have an electrode controller that controls the power and discharges flow because it prevents the battery from exploding and overheating. The electrolyte between the cathode and anode is the significant difference between the lithium-ion and lithium-polymer batteries.
The electrolyte in the lithium polymer battery is a polymer material instead of a liquid. The lithium battery is also made up of three main parts: a dry solid, a porous chemical compound, and a gel-like electrolyte is made up of a polymer.
Lithium polymer batteries are now widely used in laptops, computers, and electric cars. Still, the big problem is that most companies don’t provide you with original lithium polymer batteries because they provide you with lithium-ion polymer batteries and people cannot distinguish them.
Both of these batteries have their pros and cons, but to know which is efficient and which does not have enormous benefits, we need to see the merits and demerits of these batteries.
Merits of Lithium-ion battery
The lithium-ion battery is cost-effective, which means that you can manufacture this battery on average money; you can use this battery for a long time.
Lithium has a high power density, which makes it store more energy; the lithium-ion battery can hold three to four times more charge than its size, which is mainly used in portable gadgets.
Lithium-ion batteries have a higher life span than lithium polymer and other storms, and they can last for more than four years.
The lithium-ion batteries are easy to maintain, and there is no need to invest a lot of money in maintaining these batteries.
Another good thing about lithium-ion batteries is that they have a constant voltage, even if the load is too high, and will remain constant.
Demerits of Lithium-ion Battery
We know that if a product provides you benefits, it also has some disadvantages; here are some drawbacks of lithium-ion batteries.
One of the bad things about lithium-ion batteries is that many lithium-ion battery users face their efficiency decrease with time and this problem.
The lithium-ion batteries are ideal for rough usage because they don’t have the advanced robust technology; you cannot puncture these batteries as they are using the liquid electrolyte, which is not easy to press.
One drawback of using lithium-ion batteries is that they are not suitable for higher temperatures because of the chance of explosion. But the electronic controller is used to maintain the battery inside temperature to prevent any danger.
Merits of Lithium polymer Batteries
The good thing about lithium polymer batteries is that they are highly safe because they are covered with a protective layer of aluminum that prevents them from exploding.
These batteries are highly portable because they are lightweight and don’t have heavy-weight liquid electrolytes.
Lithium polymer batteries are available in different sizes and shapes because they are very versatile; the manufacturing can give size and shape to the lithium polymer battery according to their own.
The lithium polymer batteries are thin and have a large capacity to store the charge, and they will not discharge even when you are not using them.
Demerits of Lithium Polymer batteries
The lithium polymer batteries are expensive compared to the lithium-ion batteries with the exact specifications.
The energy density level of the lithium polymer batteries is lower than that of lithium-ion batteries, and they also have fewer recharge cycles.
Their life span is shorter because they cannot last longer than the lithium-ion battery.
Lithium Ion or Lithium Polymer- Which Battery Is Better?
It is tough to say which battery is better than the other one because both have their benefits and disadvantages; if you are looking for a battery that can last for a long time, then you can go for a lithium-ion battery. On the other hand, if you want a safe battery, your choice is lithium polymer. Both batteries can be used for high power, like how they are used in the automobile and aerospace industry.
But if we go into depth, it is not wrong to say that lithium-ion batteries are more popular than lithium polymer batteries and have more benefits. Now, most companies prefer to use lithium-ion batteries because of their lower cost.
Lithium polymer batteries also have their benefits, like they are safe to use and easy to transport anywhere. They can be built into different sizes and shapes according to the need; they can be manufactured in large and small sizes. The chances of leaking these batteries are approximately zero because they use a gel-type electrolyte made from a polymer material.
The energy density of the lithium polymer batteries is also lower than that of lithium-ion batteries.
Conclusion
The difference between Lithium-Ion batteries and Lithium Polymer batteries depends on their characteristics, features, benefits, and demerits. Both of these batteries are used in the power sector, like in the automobile industry, electronics, and many other things. The lithium-ion batteries are considered more beneficial, because of their features, like lower cost, high power density, and long-lasting. But on the other hand, lithium polymer batteries also have their merits, like they are safe and easy to transport.
