What is Lipo Battery and its Application? Without Lipo batteries drones probably wouldn’t exist today. With appealing attributes such as low weight, high energy density, and ever greater discharge rates, Lithium-Polymer (LiPo) batteries have transformed the electronic world. The emergence and continual improvement of these batteries has provided a significant performance boost in many electronic applications. These batteries have been gaining popularity and if used properly they can be used for a long run.
What is a Lipo Battery? A lithium polymer battery, or more correctly lithium-ion polymer battery, is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. High conductivity semisolid (gel) polymers form this electrolyte. These batteries provide higher specific energy than other lithium battery types and are used in applications where weight is a critical feature, like mobile devices and radio-controlled aircraft.
Just as with other lithium-ion cells, LiPos work on the principle of intercalation and deintercalation of lithium ions from a positive electrode material and a negative electrode material, with the liquid electrolyte providing a conductive medium. To prevent the electrodes from touching each other directly, a microporous separator is in between which allows only the ions and not the electrode particles to migrate from one side to the other.
Why are Lipo batteries used? When compared to their old NiCd/NiHm batteries, there are 3 main points that make them a better option: 1.
Have nearly double the capacity with half the weight of NiCd or NiMH battery packs
2.
Retain charge significantly longer than NiCd or NiMH batteries when not being used
3.
With LiPo cells in combination of series and parallel, LiPo packs can be built to power most all RC aircraft.
We use Lithium Polymer batteries in drones or any other multirotor systems as well as in fixed wing drones. The same batteries are used in our smart phones. BLDC motors needs high current or a burst of current for a moment. This high current flow capacity depends on the discharge rate of a particular battery. So, here, one thing gets confirm that you need a battery with high discharge rating which is described on a battery with a suffix “C” (30C). So that 30 C is discharging rate. This is something that you can get from Lithium Polymer batteries. The other advantage of LiPo battery is, they have higher mAh capacity. Moreover, your requirements of higher mAh as well as higher current flow gets fulfilled by the batteries that are low in weight. These are the reasons why LiPo batteries are used in drones. Lipo batteries are used in many devices. Some of them are: Health & Fitness Devices Phone & Accessories High-tech Smart Design. Drones PCs/Laptops. Most modern LiPo chargers use something called balance charging. Balance charging is just a way of monitoring the voltage on each of these cells and charging them individually. It is the best way to recharge these batteries. Chargers that have balance charging take care of this automatically.
