What is the difference between Li-ion and Li-Po battery?

What is the difference between Li-ion and Li-Po battery?


So today we are going to talk about a very important part of the electronics industry and without it, I guess all our electronic equipment like smartphones, laptops, desktops, printers, and many other gadgets will be considered as dead. Yes Batteries, batteries play a very important role in keeping our devices juiced up. Today we are going to take a closer look at the batteries, the types, how they work, and how are they different from each other.

So whenever we talk about batteries or when we purchase a new electronics device we always come across these terms: Lithium-Ion (Li-ion) or Lithium-Polymer (Li-Po) batteries. But you ever thought about what these terms Li-ion and Li-Po mean? Don't you worry we're just about to find out about these terms in a minute?

But before we go ahead make sure you follow the blog on Twitter and also press the bell icon so you are first to know whenever a new article drops. With all that said let's jump right on today's topic.

Difference between Lithium-ion and Lithium-polymer battery

HOW LITHIUM-ION BATTERIES WORK?

Lithium-ion batteries are way old than we know. Lithium-ion batteries first developed back in 1912, but they came to lime-light in 1991 when SONY started to use them heavily. Since then, one can find li-ion batteries in a wide range of daily use gadgets from music players, cameras to smartphones. Due to its very high energy density and lack of "memory effect" (in which cells become difficult to charge over time). And due to their cheap availability, they are so successful and known to everyone in the world.  
In Li-ion batteries, two electrodes one positive and one negative are placed separated in a liquid electrolyte, like ethylene carbonate or diethyl carbonate. One thing is definitely to consider that, the capacity of these batteries decreases over charge cycles and even drains off when your device is in idle condition too. And one should keep away these batteries from direct sunlight or extreme temperatures because these get unstable at high temperatures and may catch fire in some cases as well. To tackle this kind of situation electronic controllers are often used to keep the temperature within limits. 

HOW LITHIUM-POLYMER BATTERIES WORK? 

Lithium-polymer batteries came in exitance right after lithium-ion batteries, somewhere around in the 1970s. In these batteries, we have again two electrodes one positive and one negative, but here for electrolytes, a dry solid, a porous chemical, or a gel-like electrolyte is used instead of a liquid electrolyte. Thus making these batters a bit more flexible, more robust and rough in design, and very minimal of leakage electrons, thus making overall lighter and safer. But all this comes at a high cost. This battery type is costlier than that of lithium-ion. Like lithium-ion, in this type of battery technology, some sort of protection circuits also being employed to keep operating voltage under control. 

So, What is the difference between lithium-ion and lithium-polymer batteries?

OR

Which is better: Lithium-ion or Lithium-polymer batteries?

The main and key difference the lithium-ion and lithium-polymer batteries are the types of electrolytes used in both of them. Li-ion battery uses a liquid electrolyte, whereas lithium-Po battery uses a gel type(semi-solid) of electrolyte. Apart from this both have their pros and cons as well. 

Lithium-Ion batteries are relatively high in power density and costs lower lithium-Po batteries. On the other hand, the downside of lithium-ion batteries is gradual self-discharge, leakage of electrons which causes overheating issues. 

On the other hand, lithium-Po batteries are more robust and flexible, a slow self-discharge rate, super lightweight, lower chance of suffering from leakage electrons thus making them much safer than lithium-ion batteries. talking about the drawbacks these are much costlier than lithium-ion batteries and have lower energy density than lithium-ion batteries. 

CONCLUSION

So this was all about the difference between lithium-ion and lithium-Po batteries. I hope now got a fair idea about which is better: lithium-ion battery or lithium-polymer.

RAM or Processor: What makes a smartphone fast ?

  Hello friends and welcome again to your own tech guide: Techanalysia. So today we are to going to see that, what makes a smartphone fast? Is it RAM or Processor? One can't choose between RAM and Processor while determining a device's performance. RAM or Processor: What makes a smartphone fast? The answer to the above question is, both. RAM and Processor are both responsible for the smooth and lag-free performance of your smartphone. Let's take a look at how these two play an important role in a smartphone. First thing first, the type of rams used in smartphones are DDR RAMs.  In particular, the RAM used in smartphones is technically called LPDDR RAM. This term stands for 'Lower Power Double Data Rate RAM. These LPDDR RAMs are the version of DDR RAMS specially designed for smartphones. These RAMs are optimized for low power consumption because these RAMs are used inside smartphones which are having a small battery compared to PC/Laptop in which DDR RAMs are employed. T

HDR10 vs HDR10+ vs Dolby Vision: Which is best?

  HDR10 vs HDR10+ vs Dolby Vision: Which is best? So, last time we discussed the different display types in televisions currently being employed and how you could choose the perfect one according to your need and budget. And today we're here to discuss another important feature which you should look for before buying a new television. In the past few years, the television or technology behind television improved drastically from old CRT televisions to LCD televisions and then modern-day LED televisions, a lot has been changed throughout the years especially in the picture quality and a TV feature which makes the images and videos more appealing and life-like on your TVs is 'HDR'. And today we're going to discuss:- What is HDR? How HDR works? And, different types of HDR formats/standards. But before we go ahead  If you like the content that I produce, don't forget to follow the blog for awesome content like this, and do follow techanalysia on  Twitter  and press th
