Although we use lithium-ion polymer batteries every day, do you really understand it? Lithium-ion batteries are important in several categories, which one is used on cell phones and rechargeable batteries?

    Lithium ion polymer battery classification

    Now the more widely used lithium-ion batteries are important in two categories: one is the polymer lithium-ion battery, like the iPhone and other smartphones with polymer batteries; second is the lithium-ion battery, represented by 18650 battery, this battery is similar to the common 5, in the rechargeable battery, high-end balance car used more.

    Lithium-ion batteries use a liquid electrolyte, while polymer lithium-ion batteries are replaced by a solid polymer electrolyte, which can be either solid or semi-solid (gel).

    How do we differentiate?

    The hard aluminum or steel case outer packaging is the liquid lithium-ion battery, and the aluminum-plastic film outer packaging is the polymer lithium-ion battery. The silver aluminum plastic film is lighter and thinner, like a piece of paper with the same effect of folding and bending. The hard shell is usually a steel or aluminum shell, and the shape of the shell is fixed and cannot be folded or bent.

    Which one is better?

    Theoretically, the polymer lithium-ion battery is the highest technology lithium-ion battery, better than the 18650 battery, but not absolutely, 18650 battery also has the advantage of making people can not refuse.
