Batteries are one of the foundations of our life. Think about it. almost in every part of our day, we need batteries. Let’s get deeper. No doubt about that we live in modern community and most of the jobs today need to be done by computers. During the pandemic, most of the jobs are remote now. In this type of work, we found many bugs in our work. One of the bugs is our laptop batteries. It’s so exhausting when we must sit next to a power outlet because of our laptop batteries. Technology is going to make life much easier and bring more comfort to our life. So this sentence is also true for our batteries.

Let’s get deeper into this and see what new technologies are about the new generation of batteries.

New generation

As always, technology comes to help people. For this subject, technology helps people to work and use more from their laptops and mobile phones.

Older generations are called NiCad batteries that use in the 90s. At that time the NiCad batteries were an amazing product. But these batteries had some problems. NiCad batteries had very low resistance and they could supply high currents. This feature made them more popular at that time. But one of the most disadvantages of NiCad batteries was the memory effect. These batteries need to be fully discharged before recharging. If the batteries are recharged without a full discharge, the efficiency of these batteries will be greatly reduced.

After the NiCad batteries, the new generation become into the market:

• Lithium-ion battery-round and cylindrical (Ex: Asus laptop, Sony laptop, Lenovo laptop, and Samsung laptop)
• Lithium-ion polymer battery (Ex: Mac laptops, Microsoft surface, some Asus laptops, and Lenovo)

Lithium-ion battery-round and cylindrical

The first usage of Li-ion batteries was for cameras and walkmans. At that time Li-ion batteries were the best choice in the market. Because they had a good price and great efficiency. Over time these batteries make some progress and they proceed with knowledge. These batteries have a lot of types that depend on cells. Now Li-ion batteries are available with 6 and 9 cells. Thanks to Li-ion you can use your laptop for 6 hours.

Advantages

• Long life
• Lightweight
• High energy storage
• Do not need to be completely discharged before recharging

Lithium-ion polymer battery

These batteries are probably the best thing that can happen in a new generation of laptops.

The term polymer is commonly used for some lithium batteries. You've probably heard the term polymer battery by now. The cell structure of lithium polymer batteries is made of compressed plastic. Li-PO batteries differ from other batteries in terms of the electrolytes used. The original polymer design, which it back to the 1970s, used electrolytes that were very similar to the film tape of older cameras known as dry polymer or solid polymer electrolytes. These electrolytes had poor conductivity at normal room temperature and required 60 ° C for proper performance. But in the new models, this problem has been solved.

features and advantages

Li-Po batteries are the best choice for usage in laptops. Each polymer battery is significantly lighter than an ion battery.

They have fewer limitations than conventional lithium-ion batteries. This type of battery is very versatile due to its lightweight and flat shape. The invention of this battery was a great leap in the evolution of the laptop battery.

What is the difference between the new and old generations of Li-Po Batteries

The amount of released energy in the new lithium polymer batteries is higher than the old models and the dimensions of the cells are smaller.

On the other hand, the cost of making new polymer cells has increased. The new polymer battery cells are packed in a thin, flexible foil, while the old polymer lithium batteries used multi-layered, durable sheets to wrap the cells. The foil cover makes the newer batteries weigh less than the old ones.

Where to use

These batteries are placed in the back of the keyboard panel inside the laptop, and also these batteries are thin and light. Because of these conditions of Li-Po batteries, they are good choices for use in modern and newly made laptops. Because the companies are trying to build light and efficient laptops. For example, we can see these batteries in our Asus laptop, MacBook, and Microsoft surface laptops.

?What is the battery life of Li-PO

Lithium polymer technology has been a valuable breakthrough in the manufacture of lithium batteries. But polymer batteries, like others, have their own useful life.

The life span of polymer batteries is about 300 charge cycles. It means that you can charge the battery 300 times and use it to completely drain the stored energy and reconnect the battery to the charger. However, accurate measurement of the life span of these batteries is not possible. Because in different conditions, different amounts of charge are discharged from these batteries. Many manufacturers have stated that polymer batteries can last for an average of about two or three years.

Fortunately, nothing will happen when the battery life is over. The only problem you will see is that it can hold only up to 80% of the charge.

Advantages

• Do not need a full charge
• Charging with USB port
• More safety
• Lighter than other models
• Thinner than other models
• Longer life span than other models

The generations of batteries come a long way to become what is it today. At first in last of the 70s, people use big AA batteries for computer. In the 80s and 90s, the generations of NiCad became and make a revolution in this industry. And now lithium batteries and all of the types of them make the new laptops more efficient and also bring more comfort for us. You can see more specifications of these batteries in Meghdadit. You can gain more knowledge and information from Meghdadit. If you have trouble with your laptop battery, you can order a new one in Meghdadit.
