Lithium-ion battery contains liquid lithium ion as an electrolyte, whereas lithium polymer contains solid or gelatin-like polymers as electrolyte. Both these batteries have their own pros and cons. Let's have a look at the differences between Lithium ion and lithium polymer batteries in order to understand which one is more suitable as per the requirement.

• Lithium-ion batteries are known for their high energy density as compared to Lithium polymer batteries.
• Lithium-ion batteries have a tendency to convert 75% to 85% of battery to actual power, while Lithium polymer coverts 75% to 85% of it to actual power.
• Lithium polymer battery has a shorter charging duration as compared to Lithium-ion battery.
• Lithium-ion batteries are less expensive as compared to Lithium polymer batteries.
• Lithium polymer batteries are easier to carry as they are lightweight. Lithium-ion batteries are heavier.
• Lithium polymer batteries have better safety features as compared to Lithium polymer batteries. This minimizes the chances of an explosion.
• The charging capacity of the Lithium polymer battery lasts much longer. Whereas, Lithium-ion battery loses its charge as it ages, even when it is not being used.

 

Lithium polymer is a more advanced type of battery. However, it has its own advantages and disadvantages. Lithium-ion, on the other hand, has time to time upgrades.
