Many households and others use Lithium Polymer batteries for Powering devices

Many households and others use Lithium Polymer batteries for Powering devices, equipment, vehicles, and many more. We use these types of batteries on a daily basis. Sometimes it results in some sort of disaster, which is because we don't understand how ambient temperature can affect the performance and safety of the lithium polymer battery.

Before going to the main topic of the blog, let's discuss what a lithium polymer battery is.

lithium polymer battery:

Lithium-ion polymer batteries, or LiPos, are one of the most commonly used batteries nowadays. It is a rechargeable battery that uses lithium-ion technology. Through this technology, it can be recharged repeatedly. Lithium-ion polymer batteries consist of diverse electrochemical cells. During the discharge process, the lithium ions migrate from the negative electrode to the positive electrode through the electrolyte. The process gets reversed when the battery tries to charge again.

Right now, this simple process is used in almost every battery, including lithium-ion polymer batteries, which are used in mobile phones, and now in more wearable devices like smart watches.

However, if you are using lithium polymer batteries, then there is something that you must know to properly maintain the battery in any condition. Moreover, this will save you from any sort of mishap that we often see with batteries.

What temperature is safe for lithium polymer batteries?

If you are a regular user of Lithium polymer batteries, then you must know some of the facts about these types of batteries, especially the preferable temperatures. Batteries are very sensitive to temperature; most of the companies might have informed you of some safety precautions, but let's be honest, we don't listen to those. So here we are giving some temperature terminologies about Lithium polymer batteries.

Sometimes, because we use batteries at high electric current, faster voltage decay speeds, overload of the high current, and many more factors cause the batteries to suffer some damage. So the ambient temperature invariably has a great influence on the performance of the battery, and a lower temperature results in a lower discharge platform and efficiency.

The best temperature for lithium polymer batteries is between 0 and 35 °C. There are different temperatures that vary while charging and discharging a lithium-ion battery.

Temperature During Charging:

●The charging temperature should be between 5 and 45 °C.

●It is highly recommended to charge the battery at room temperature.

●Always remember that you shouldn't charge the battery immediately after the high-temperature discharge.

●You must use the charger that comes with the battery. Don't use any other charger.

Discharging:

●The best temperature during discharge ranges within 45 °C;

●The Discharge current shall not exceed the maximum current identified in the battery specification.

●If the battery is having a high-temperature discharge, it must not exceed 70°C.

●Never expose the battery to the sun while charging or discharging. It should not exceed 45 °C.

Do lithium batteries work at low temperatures?

Well, most of the devices that come with lithium batteries have done a lot of engineering so that they can work at low temperatures. Besides that, if we look at the battery alone, it will not work for too long at low temperatures. In fact, the low temperature will reduce the effect of lithium ions, the discharge capacity will be weak, and the overall use time will shorten. If you are using a lipo battery at a low temperature for a short period of time, then the damage is temporary and will not cause any damage.

Although there are chances that the charging and discharging of batteries in a low-temperature environment for a long time will result in

"The metal lithium will be separated out on the surface of the battery anode."

This process can permanently damage the battery's capacity. So be aware of that. In fact, we often see our smartphones or smart watches turn off at low temperatures. It is due to the same reason.

Does heat affect LiPO batteries?

Either we are using lithium-ion batteries in cold temperatures or in hot temperatures. Although there are certain limits for each one of them. You can't use lithium-ion batteries at very low temperatures; likewise, you can't use them at high temperatures.

Too much heat affects the lithium-ion batteries and can cause severe damage to them, which may not be repaired ever again. You cannot use the lithium-ion batteries above 70 °C, especially while discharging.

Usually, most places don't have that sort of high temperature, but the environment where you use the battery may affect the battery or device due to the constant heat. Exposing the battery to the sun while charging or discharging may wreck the battery badly due to the high temperature.

FAQs:

What is the best temperature to use lithium-ion batteries?

The Best temperature to use lithium ion batteries is between  5 to 45°C. You can use it at higher temperatures than that, but it must not exceed 70 degrees.

Can low temperatures cause damage to the lithium-ion batteries?

Low temperatures cause slow damage to the lithium-ion batteries. In fact, if you use it for a short period of time at a low temperature, it will not affect you that much, but it will affect you a lot if used for a longer period of time.

Are lithium-ion batteries safe?

Yes, lithium-ion batteries are the most commonly used batteries in the world. It is used in almost every electronic device, vehicle, and more. They are completely safe to use under the temperature conditions given.

Final Viewpoints:

Lithium-ion batteries are the most commonly used batteries in the world. They are sensitive to very low and very high temperatures. Although you shouldn't be worried about it because these temperatures don't usually occur in our environment, Keep using it at room temperature, which is the best temperature for lithium-ion batteries.

These are some precautions that you must know if you are using lithium polymer batteries. Keep those in mind while using it, and give the best environment to your battery for maximum output.
