Lithium polymer batteries have the same technology used by liquid lithium ion batteries. In other words, the anode and cathode are of the same type. The only difference is that these units use an aluminum plastic film and gel electrolytes. Therefore, these power packs are thinner and lighter but offer higher power density. In this article, we are going to talk about 10 advantages of these power packs. Keep reading to know more.
1. High energy density
Compared to nickel-hydride or nickel-cadmium batteries, lithium polymer batteries are 50% lighter. But they have the same degree of energy density, which makes them an ideal choice.
2. Slim design
The liquid lithium ion battery features a custom case and positive/negative electrodes. And then there is a technical limit that does not allow batteries to be thinner than 3.6mm. On the other hand, polymer cells have no such limitations. Therefore, the thickness of these units can be less than 1 mm.
3. Low internal resistance
Unlike liquid batteries, polymer batteries have less internal resistance. Therefore, these batteries can help extend the time your applications can stay in standby mode. So this is another great advantage of these units.
4. Customizable shape
Depending on demand, polymer batteries can be made thicker or thinner. For example, for special smartphones, manufacturers may require thinner batteries. This can help you make the most of available space and still enjoy a long backup.
5. Good charge/discharge rate
If you use the correct type of charger, you can recharge these units in just two hours. Basically, polymer batteries use colloidal electrolytes that have a stable discharge rate, unlike liquid electrolytes.
6. High voltage
A lithium polymer cell has an operating voltage of 3.7v on average, which is equivalent to three nickel-hydride or nickel-cadmium cells connected in series.
7.High security and performance
The outer shell of these batteries is made of aluminum plastic. On the other hand, liquid lithium ones come with a metal casing. Due to the flexible packaging, deformation of the outer shell will not cause the battery to stop working.
8. Long life cycle
Under normal circumstances, a lithium polymer battery tends to be charged and discharged more than 500 times. Therefore, you can enjoy a long life cycle if you opt for these power plants.
9. No pollution
Additionally, lithium polymer units do not contain harmful metals such as mercury, lead, or cadmium. Therefore, they do not cause pollution unlike other types of units.
10. No memory effect
Nickel-cadmium batteries tend to lose their discharge over time. On the other hand, lithium polymer ones don’t have that problem. This is also called memory effect. Over time, the market share of these power packs is increasing due to the list of advantages these batteries offer.
Furthermore, these batteries are also used in power tools and laptops. Therefore, these are becoming quite popular as time goes on.
In a nutshell, these are just 10 of the most common advantages of lithium polymer battery packs. Hopefully this article will help you get a deeper insight into these units.
