According to the electrolyte materials, Li-ion battery divided into liquid lithium ion battery and polymer lithium battery or plastic lithium battery. 

In this blog, we’re going to review about the differences between Li-ion and Li-polymer battery.  we hope to give you the information you need to make the best possible choice!

Lithium-ion Battery

The most significant difference between lithium-ion and lithium-polymer batteries is the chemical electrolyte between their positive and negative electrodes. Both lithium-ion and lithium-polymer batteries have their pros and cons. Typically, the advantages of a lithium-ion are their high power density and lower cost than lithium-polymer battery. Lithium-ion batteries are incredibly efficient.  Li-ion in a more flexible casing. 

Lithium-ion batteries are inherently unstable, suffer from aging, and are potentially dangerous. As Li-ion batteries have become more popular in

Lithium-Polymer battery:

On the other hand, Li-Po batteries are generally robust and flexible.  Especially when it comes to the size and shape of their build.

They are also lightweight, have an extremely low profile and have a lower chance of suffering from leaking electrolyte. But Li-Po batteries aren’t perfect as they are significantly more costly to manufacture and they do not the same energy density nor lifespan as a lithium-ion.

Lithium-ion Battery vs Lithium-polymer Battery

In the below table, we covered all the parameters of both lithium-ion and lithium-Polymer battery.

Parameters	Li-ion battery	Li-polymer battery
Usable voltage range	from 3V to 4.2V	From 3V to 4.2V
Energy density	High energy density	Low and decreased cycle count compared to Li-ion
Flexibility	Low	High
Weight	Relatively heavier	Light weight
Safety/Explosive risk	More volatile as compared to Li-Po	More safety. Less chances to explosion
Charging duration	Relatively longer charge	Shorter charge
Cost	Cheaper	Slightly expensive
Capacity	Relatively lower	same volume Li-Po batteries, capacity is around 2 times of Li-ion battery
Life span	Long	Long
Aging	Loses actual charging capacity over time	Retains charging capacity better than Li-ion
Temperature range usage	-20 to 60º C	-20 to 70º C
Impedance	<100 mΩ	<50 mΩ
Charge temperature	0 to 40º C	0 to 40º C
Storage temperature	-20 to 35º C	-20 to 35º C
Applications	Used in power backups/UPS, Mobile, Laptops, and other commonly used consumer electronic goods. Also used in Electric mobility and Energy Storage Systems	Mostly used i radio controller equipments and aircrafts,Mobile, laptops and other commonly used electronic products. Also, used in Electrical vehicles.
