The Difference Between Lithium-Ion And Lithium-Polymer Batteries

There is an endless debate between the lithium-ion and lithium-polymer batteries about which one is better than the other from modern consumer electronics. These two types of batteries, however, have very distinct differences from one another that makes it very difficult to determine which one is better.

While everyone might not be able to settle this score, but once and for all, let us give you the best information that you have to know about the differences between a lithium-ion and lithium-polymer battery, its pros and cons and other important stuff that makes them very different or rather unique from one another.

The Differences

When it comes to the differences between a lithium-ion battery and a lithium-polymer battery, the former can be recharged and is now being mainly used in many electronic devices today. Lithium-ion batteries have a group of electricity generating compartments that is composed of three main pieces, the positive electrode, the negative electrode, and an electrolyte or a liquid chemical compound in between the two pieces. Majority of lithium-ion batteries have its own electronic controller that regulates power and the discharge flow so that it will be prevented to overheat and explode.


What makes lithium-ion batteries totally different from the lithium-polymer batteries according to RCTopgeek is the presence of the electrolyte chemical compound in between the positive and negative electrodes while the lithium-polymer batteries do not have a liquid electrolyte in it, and instead, it uses three dry solid forms that are the porous chemical compound, or a gel-like electrolyte, that is mostly used in electric cars and laptop computer batteries.

Which one is better?

Like what is mentioned above, both lithium-ion and lithium-polymer batteries have their own advantages and disadvantages, and usually, the advantages of a lithium-ion battery have a very high power density but lack the memory effect or the ability of the battery to become harder due to charging over time. Also, lithium-ion batteries are cheaper than lithium-polymer.

However, there are particular cellphone brands that are not allowed for flights especially those that use lithium-ion batteries which are susceptible for being unstable and suffers badly from aging and use and can potentially dangerous if carried on board a plane. This is due to the separation between positive and negative electrodes that breached and causes a chemical reaction that combusts fire. However, there are already changes and strict safety features that were added to this kind of batteries nowadays which can be carried on board a plane.

Lithium-polymer batteries, meanwhile, are robust, and very flexible and comes in different sizes and shapes according to its built. It is also lightweight and has a very low profile that prevents any electrolyte leakage. Lithium-polymer batteries are widely used in electric car batteries and portable power banks. The only downside of lithium-polymer batteries is its lack of the same energy density that can be stored compared to the lithium-ion.

Both batteries have their own distinct advantages and disadvantages that make them unique from one another, but the real point here is you, the consumer should use it with the proper device so that you can fully maximize its capacity as a source of energy.
