Can Lithium Battery Freeze

Posted by Brian Babor on February 27th, 2023

The short answer to whether or not a lithium battery can freeze is yes. In extreme temperatures, the temperature of a lithium battery can drop to temperatures lower than those found in subzero climates, increasingly the chances of the battery freezing.

However, this risk can be somewhat negated through proper storing and care. Extreme hot or cold conditions can produce electrolyte freezing within the battery, causing a decrease in ionic conductivity and in turn, the efficiency of the battery itself. If the battery does freeze, it could result in permanent damage to the device due to electrical shorts.

It is important to store lithium batteries in an ideal environment. Anywhere between 15°C to 25°C is ideal and storing them in temperatures above 30°C should be avoided as much as possible. Use of a battery protection circuit is also recommended; this circuit can provide an additional layer of safety by preventing the battery from overcharging or discharging, exercising greater control and balance over various factors such as the battery's temperature.

For those operating in subzero climates, it is important to understand how the temperature affects the lithium battery and the device it powers. When temperatures drop below 0°C, the battery can freeze, and if the battery is partially drained and left to face the same temperatures, it can cause permanent damage to the lithium cells themselves. Therefore, keeping the battery charged up and in good working order as much as possible is extremely important for extending the life of the battery.

Overall, lithium batteries can freeze, and can be damaged if left in subzero temperatures. Therefore, to decrease the chances of this happening, understanding the ideal temperature range for the lithium battery, using a battery protection circuit, and maintaining the battery’s charge are all important for extending its life and keeping your devices running in extreme temperatures.
