Batteries especially the ones from the Lithium family can be pretty hard to understand at times. So we have decided to explain it to you in simple terms. First of all, there are three types. The first one being the li-ion battery, the second li-ploy, and the third lithium-ion polymer battery.
The Lithium-ion battery started appearing in 1912 when they were first developed. However, they became really popular in 1991 when huge companies started using them. The first company to use lithium batteries was Samsung. These batteries had a high-density charge and were way less expensive than the li-polymer batteries. They have a long shelf-life. They do not discharge easily and the best part is that they have a very long lifespan. They are good to use for 300 to 400 charging cycles.
Lithium polymer batteries are slightly more expensive than their ion counterparts. They were developed in the 1970s. The first included a dry solid polymer film as an electrolyte. Hence, they were very thin yet very powerful. They could stay charged for a very long time and not take up a lot of space. Other than that, they are very lightweight and are very safe. But their density is very low as compare to the li-ion battery. They are also very expensive to produce.
The lithium-ion polymer battery is a very powerful rechargeable battery. It uses a lithium-polymer as an electrolyte instead of a liquid electrolyte. These polymers are made with a semi-liquid gel-like polymer instead of a solid polymer, unlike the li-poly battery. This device carries a higher degree of specific charge and due to it being almost weightless, it is employed in devices where weight is an important feature. The voltage of a Li-Po cell is somewhat between 2.7 volts to 3.0 volts. It also has numerous applications including radio controlled equipment, personal devices, and electrical devices.
Which battery is better Li-polymer or Li-ion?
The most heated debate of the modern consumer electronics has to be the one between Lithium polymer and Lithium-ion. So we decided to take part in it. We will first learn about the differences between the two and then analyze the situation to find a better battery.
Both the lithium-ion and lithium-polymer were developed around the same time. But lithium-ion took off before the other one because they were adopted by large companies. Both the batteries have three parts like the normal ones. These parts include a negative and a positive electrode and an electrolyte. Most lithium batteries have a power regulating component in them that stops the battery from excessive heating and regulates the temperature.
The manufacturing of both the ion and polymer is very different. Equipment and tools for lithium-ion batteries are very expensive and automated. Mostly the cylindrical configuration is used to produce as it is the most widely used batteries in most companies. The lithium polymer cell, on the other hand, is less expensive to do. Because the equipment and tools are not very costly. As it is a flat cell, the assembly is pretty quick and cheap. As it is a pouch cell, the lithium polymer batteries have a wide array of pouches to choose from. Even bendable batteries can be developed. All of the internal space of a pouch is filled to its maximum capacity within a battery pack.
However all these differences do not matter much, the main difference is between the electrolytes. The electrolyte in lithium-ion batteries is liquid but the electrolyte in the lithium polymer is a solid sheet of polymer.
But it is not possible to determine which battery is better than the other. Both have their own set of pros and cons. The main advantage of lithium-ion batteries is that they have a higher density charge but it does get harder to charge over-time but it costs way less than the other. Lithium polymer is robust and flexible, lightweight and generally a low profile. But in terms of cost, these are more expensive than lithium-ion.
However, lithium-ion batteries are more popular in consumer electronics and are most widely used.
What is a li-ion polymer battery?
Lithium-ion polymer battery is usually called LiPo or Li-poly batteries. It is a lithium-ion battery that uses polymer as an electrode and is rechargeable. The polymer electrolyte is gel-like instead of a liquid. The gel of high conductive nature polymer. They have a greater degree of specific charge and are housed in batteries that are weight dependent.
The working is almost the same as lithium-ion. The intercalation and de-intercalation of lithium ions on the negative and positive electrode. To separate the two, a film of semi-liquid electrolyte is arranged in the middle.
There are various applications of the Li-polymer batteries including the radio-controlled equipment including aircraft, remote-controlled toys, etc. Another huge application is personal applications such as very thin laptops or personal assistants, portable media players, remote controllers for video games and e-cigarettes. Also, lithium batteries are the most widely used in electronic cars. The biggest consumer Japan produces lithium polymer batteries in bulk every month!
How long does li-ion polymer battery last?
Like any other Lithium powered batteries the Lithium-ion polymer batteries can also only last for 2 to 3 years. That is almost 400 or 500 charging cycles. One charging cycle is the time between one full charge and then the full time it takes to gets discharged and then fully recharged again. Hence, life expectancy is almost two to three years and even more if used with care.
Even if they are shelved. They have a long life of lithium-ion batteries. It gets charged in one normal cycle. It has a very low self-charge, and that also contributes to its long life. The self-charge is almost half of the nickel batteries.
