What Are Li-Polymer Batteries Used For?

When people talk about portable gadgets and gizmos, one of the first specs they look into is the battery life. If your device gets drained fast, you won’t get to use it for so long. So scientists and manufacturers are always innovating to create better batteries. And Li-polymer batteries are one of these innovations.

What Are Li-Polymer Batteries?

Li-polymer or lithium-polymer batteries (LiPo) are rechargeable batteries that use polymer electrolytes instead of liquid ones.

But current LiPo batteries are one step away from lithium-ion batteries because they don’t use a “true” lithium polymer solid, unlike the original design in the Bell Laboratory in the 1970s because solid polymers can’t perform well at room temperature.

Devices Using Li-Polymer Batteries.

Some of the devices that use a li-polymer battery are:

Drones, Radio controlled equipment, and aircraft

LiPo batteries are now what most manufacturers of hobby drones, radio-controlled aircraft, and cars, large-scale model trains use as the power source for their products. Its increased capacity, power delivery, and lower weight are what justifies the price.

Most airsoft now also use LiPo batteries because of their higher discharge currents and energy density than traditional NiMH batteries.

Personal Electronics

Most portable devices like mobile phones, laptops, power banks, media players, wireless controllers, wireless peripherals, etc. use LiPo batteries. Such devices use specifically shaped batteries and high energy density, which LiPo batteries can provide with no problem.

Electric Vehicles

Car manufacturers like Hyundai Motor Company use LiPo batteries for their electric and hybrid vehicles, as well as Kia Motors’ electric Kia Soul. The Bolloré Bluecar also used LiPo batteries as its power source.

Uninterruptible Power Supply Systems (UPS)

Most UPS systems now use LiPo batteries. They have more benefits than VRLA batteries and have growing stability and safety improvements. UPS with LiPo batteries also benefit industries that need critical power backup but need space because of their power to size and weight ratio. They also have a longer lifespan than VRLA Batteries.

Jump Starter

Lead acid batteries are cheaper than LiPo batteries. But they, unfortunately, have a shorter life span and are much heavier. So most manufacturers are now switching to LiPo batteries as jump starters.

Lithium Polymer vs. Lithium-ion Batteries

The biochemical electrolyte within the positive and negative electrodes is the most glaring difference between lithium-ion and lithium-polymer batteries. While lithium polymer batteries use a gel-like, solid electrolyte, lithium-ion batteries use a liquid one.

Besides that, there are other distinctions between lithium polymer and lithium-ion batteries.

Pricing

When it comes to price, lithium-ion batteries win the race since it’s significantly cheaper than lithium polymer.

Versatility

Lithium polymer batteries are more versatile than lithium-ion ones since there is almost no end to their shapes and sizes. Plus, manufacturers can mold it in different ways. So product designs are not limited to their battery compartments.

High Power

Lithium-ion and lithium polymer batteries are both suitable for high power use. But lithium-ion batteries are more effective since they can produce energy at a higher level, fit for massive usage.

Robust and Lightweight

Lithium polymer batteries are more robust and lightweight than lithium-ion ones. Plus, it’s less prone to leakage because of its design.

Suitability and Portability

Even though both lithium-ion and lithium polymer batteries are compact, the latter is more portable because of its small and sleek design.

Conclusion

Lithium-polymer batteries are one of the products of modern innovation in the quest for providing an efficient power source for portable electronics that is also convenient. And scientists are still trying to improve this technology to reach new goals. So if you know anyone wondering what Li-polymer batteries are used for, share this article with them.
