The Pros And Cons Of Lithium Ion Batteries VS Lithium Polymer Batteries
The terms lithiumion batteries and lithium polymer batteries may seem exceedingly similar. However, the truth is that the two differ from each other to a great extent. Let us discuss and elaborate on their pros and cons via their differences in this article.
Lithium-ion batteries come with four major components. These comprise a positively charged cathode composed of graphite and a negatively charged anode of lithium. The other two parts include an electrolyte and a separator between the two charged electrodes.
Lithium polymer batteries have a similar setup and structure to that of lithium-ion batteries. However, they are composed of a gel-like substance or silicon graphene.
Lithium-ion batteries generally have a high energy density and get used in power-hungry applications. This attribute also increases their life cycles and lifespan. The lithium-polymer batteries have a comparatively diminished cycle count.
Versatility and Flexibility
In terms of flexibility and versatility of construction and application, lithium polymer batteries are the better option. They come in various shapes and sizes and can get used in several industries, sectors, fields, and domains. They are exceptionally robust and adaptable as well.
Lithium ion batteries are relatively heavier than lithium-polymer batteries. Hence, the latter gets used in electric vehicles and radio-controlled aircraft that require lightweight batteries.
Lithium-ion batteries have more volatile components compared to lithium polymer batteries. Thus, they can lead to small-scale fires when they get overcharged or overheated. Additionally, they are unsafe at higher temperatures.
Comparatively, lithium polymer batteries have more established safety features that protect them from any sort or kind of explosion. They have a lower possibility of leakage owing to their gel-like components.
Lithium-ion batteries take a longer time to charge than the duration that lithium-polymer batteries take. It implies that the latter is ready for use faster when both get put to charge simultaneously.
The materials used, the creation and manufacture process involved, and various other factors need consideration to estimate the cost. The ultimate result dictates that lithium polymer batteries are more expensive than lithium ion batteries.
Both lithium-ion batteries and lithium polymer batteries experience long lifespans. Nevertheless, the decay cycle of the latter is much shorter than the former’s.
Thus, lithium-polymer batteries are not as long-lasting as lithium-ion batteries.
Aging in the case of batteries does not refer to their practical maturing. It represents their charge retention capacity over time.
Lithium-ion batteries lose their charge and charging capacity with time. On the other hand, lithium polymer batteries retain both to a significant extent.
The impedance of a battery is the effective resistance that its electric circuit experiences in an alternating current. It arises due to the combined and collected effects of the reactance and the ohmic resistance. The higher the impedance, the better is the performance of the battery.
Lithium-ion batteries have an impedance of more than 100 milliohms, while for lithium-polymer batteries, it is greater than 50 milliohms.
Lithium-ion batteries find application in mobiles, laptops, electric vehicles, power and energy storage, and backup systems.
Lithium polymer batteries get used in radio-controlled equipment, electronic products, devices, and vehicles.
