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.
