Comparison between two of the most popular batteries i.e Li-ion and LiPo batteries on various parameters.
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|
|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|
|Capacity||Relatively lower||same volume Li-Po batteries, capacity is around 2 times of Li-ion battery|
|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.|
Hope this article helps you to understand the actual difference between Lithium-ion and Lithium- Polymer 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
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.
