Cold Weather Effect on Lithium Ion Battery - Introduction and Solution

LFP batteries are useful for use in any weather because they are safe to use at temperatures ranging from -4 degrees Fahrenheit to 140 degrees Fahrenheit. Lithium batteries are an excellent alternative for continuous, dependable power because some off-grid solar, RV, and Camper Van owners live and travel in extremely cold climates. 

Why lithium ion batteries are the best option for cold weather?

Any battery owner should be aware that cold temperatures can be detrimental to a battery's health. Cold temperatures can adversely impair the health and lifespan of conventional lead-acid batteries. Compared to lead-acid batteries, lithium batteries perform far better in colder climates. A lead-acid battery will typically become weaker in colder weather, the more you draw from it.

When used, LFP batteries warm up, reducing the battery's resistance and raising its voltage. When it comes to cold weather, lithium is the undisputed winner when you are trying to upgrade or solve your battery problems.

Are lithium ion batteries Good in Cold Weather?

Lithium batteries require chemical reactions to function, and the cold can impede or even completely halt such reactions. These batteries are more tolerant of cold than most other types of batteries, but extremely low temperatures still have an impact on how well they can store and discharge energy.

You will need to charge these batteries more frequently because they lose power in the cold. Unfortunately, charging them in cold weather is less efficient than charging them in warm weather because the ions that produce the charge do not travel so efficiently in cold weather conditions.

These include:

Maintaining Appropriate Temperature for Storage

Keep your lithium batteries in an area where the temperature does not rise over 80 degrees Fahrenheit or fall below 32 degrees.

Charging Regularly

Regular charging is necessary, since lithium batteries should never be left completely discharged. This is especially true in the winter months, when batteries are more susceptible to sudden power loss.

Cleaning Them up

It is critical to keep your lithium batteries clean, since corrosion and dirt can shorten the lifespan of the battery and cause them to lose charge more quickly. baking soda and water can be used to make a mild cleaning solution.

Using Premium Versions

Winter is a time when battery longevity is crucial, so make sure to get Li-ion batteries from long-lasting, high-quality brands. 

How Extreme Cold Can Crack Lithium Ion Battery Materials?

The effects of cold weather on battery life are prominent, even with lithium batteries. Lead-acid batteries provide 70–80% of their rated capacity at temperatures below 32 degrees, cold weather significantly reducing both efficiency and useful capacity.

You'll notice that your lithium battery is losing power considerably more quickly throughout the winter, especially during peak winter than it was during the warmer months. Temperatures below freezing limit battery capacity temporarily, when they get this low.

The lithium cells in your battery are unable to take the same amount of charging current as they could when the temperature was warm when the internal temperature falls below 32 degrees. When the temperature of your lithium batteries is below freezing, avoid charging them.

Lithium ions have trouble working within the graphite anode under cold charging conditions. These ions end up plating the anode's surface rather than intercalating. Plating, which lowers battery capacity and raises resistance, can happen due to battery-charging in extremely cold temperatures. If enough plating occurs, it has the potential to pierce the separator and lead to a potentially harmful cell short.

The most important piece of advice, when it comes to charging batteries in the winter, is to always reduce the charge current when the temperature drops below freezing. This can be challenging to achieve unless your charger and BMS are in communication and the charger can respond on the data sent. If you charge the battery in below-freezing conditions, you must ensure that the charge current is between 5 and 10 percent of the battery's capacity.

How to Charge Your Lithium Ion Battery in Cold Weather?

These are some important factors that you would want to consider, before trying to charge your battery on freezing winter days.

Time of Day You are Charging the Battery

Charging lithium batteries in subfreezing conditions can have detrimental long-term impacts. Thus, it is always preferable to charge lithium battery-powered devices during the day rather than at night. It is usually warmer during the day than it is at night, and daytime charging is better if you are worried that cold night temperature would keep your smartphone from charging. Also, after a battery has finished charging, leaving it plugged in for too long may be harmful to it. You would not want to leave it plugged in all night because many lithium battery-powered devices just need an hour or two to get fully charged.

Your Smartphone Case

You need to have a good smartphone case that can keep the battery safe while charging during the colder months. 

Do you own the ideal phone case for your needs and way of life? Not all premium cases are created equally, and you must get a case that is more durable than others and comes with cutting-edge technology that can shield your phone from environmental harm in temperatures ranging from 0°F to 120°F. 

Battery Storage in Mild Temperatures 

You might not have complete control over this. Knowing the proper temperature for battery storage is still crucial, though. The operating temperature range for lithium batteries is 32 to 80 degrees fahrenheit. However, they can still work at higher temperatures, albeit to a lesser extent. They may appear to lose their charge more quickly than usual.

Cleanliness of Your Battery

On warm days as well as cold ones, it is crucial to maintain your battery clean. This is vital before a prolonged period of storage. For some battery types, dirt and corrosion can seriously affect their performance and speed up their discharge. Lithium batteries so not need to be maintained. However, you have to make sure that no dirt or dust has accumulated over your phone battery.
