Did you ever think about why your phone works at all? Probably not. But, if you think about it, all portable gadgets rely on a battery to keep ticking – and some have better battery life than others. That’s why we’re going to take a peek at what keeps your phone ticking and why some batteries do better than others.
Lithium-Ion Batteries began their development in 1912. However, they did not become popular until they were adopted by Sony in 1991. Lithium Ion Batteries have high energy-densities and cost less than lithium-polymer batteries. In addition, they do not require priming when first used and have a low self-discharge. However, lithium-ion batteries do suffer from aging – even when not in use.
Lithium-polymer batteries can be dated back to the 1970′s. Their first design included a dry solid polymer electrolyte that resembled a plastic film. Therefore, this type of battery can result in credit card thin designs while still holding relatively good battery life. In addition, lithium-polymer batteries are very lightweight and have improved safety. However, these batteries will cost more to manufacture and have a worse energy density than lithium-ion batteries.
After reading all of the pro’s, con’s, and specifications of both battery types, you can see that there isn’t much of a competition here. Although the lithium-polymer battery is sleeker and thinner, lithium-ion batteries have a higher energy density and cost less to manufacture. Therefore, we obviously know which one is chosen by companies like Samsung, Apple, Motorola, and more. Finally, with new chemicals and such being added to these batteries often, who knows which will come out on top in the long run. The only thing we do know is that this phone, will be sporting a very thin and transparent lithium-ion battery.

One big minus to Li-Ion is the capability to explode at odd times. (Up next to your face, in your pocket, etc.) My understanding is that most Li-Poly battery’s do not suffer from this affliction.
I know this is an old discussion but really? I use rc cars a lot and use lipo batteries in them. I have seen them explode into flames for no apparent reason. I have never seen this with lithium ion batteries.
i’m just amazed at how little it seems battery tech has advanced over the years when compared to pretty much any other essential tech components.
Lithium Ion also degrades over use. It holds less and less charge each cycle.
Don’t forget the other reason companies like li-ion batteries… they can sell more because the second a li-ion battery is made, its dying.
LithiumIon batteries have a far superior capacity than LiPolymer. They cannot be made very flat though and so are unsuitable for phones. This article says that LiIon has better energy density in the paragraph, then states the opposite in the list :/
It says “high energy densities” not “higher than”. That sentance was only saying Ion costs less than polymer. Polymers are considered superior in capacity (not density) and that’s over time. Ion degrads faster over time so we have to buy more. Polymer is more bang for your buck over time, and less bang in your pocket or your face, as long as the corporate profit motive stays out of it (not likely). Just clarifying, no offense.
Lithium ion batteries have a higher heat tolerance, higher charge cycles, and greater life span.
i meant polymer lol
Wow, good number of likes to both the comments!
I wonder what the energy density to size ratio is though… if they were the same size is it possible that LI polymer would end up being better?
Can a charger that came with a polymer batt operated cell phone be used with a ion batt operated cell phone. I am not not battery knowledgable, but I do know that particular chargers should go specifically with the type that they are charging and shouldn’t be interused.
I guess charger may not interfere battery life span because nowadays most device charge through USB port. As long the correct voltage out from the charger does not harm the battery.
Ok 1st off – Source is Radio Shack…why do you guys feed into a system of non-original research and effort…this is a hallow article that is meant to be filler to take up your time on the Radio Shack Website. There is nothing informative above…also….you guys in the comments and the author are all hella stupid….Lithium ION is a family of batteries that also includes Lipo batteries too! Its like saying “Atoms are better than Hydrogen!” WTF???? Notice how Wikipedia references a LIPO as a Lithium Ion Polymer Battery?
I’d like buy Asus n550jv. it’s expensive(“not good :( ” ) and its config is very good,but there is a big problem.this laptop had Lithium-Polymer Battery and I don’t know what I must do ? Is it so big problem?
Lithium polymer are used for powering of electric r/c planes. I wonder if it is because of the higher discharge rate.
This article is very, very poor. Lithium-Polymer batteries have 20% or higher energy density than Lithium-Ions. That is why a smaller Li-Poly battery can have the same capacity as a Li-Ion. It is also one of the reasons they are more expensive. If you read the source material for this article, you can see that “energy density” was mentioned as an advantage over Ni-Cad batteries, not Li-Poly.
Can I use Li-ion battery instead of Li-polymer ???????? I have mobile phone which has battery of Li-polymer cell and it is damaged so in the market battery with Li-ion available can I use it???????
how is lithium-ion/ lithium-polymer different from lithium-ion polymer??
