How Does The Temperature Affect Lithium Batteries?

Lithium ion batteries are commonly powering an array of devices, equipment, and vehicles. Room temperatures have a direct bearing on the internal temperature of lithium ion batteries. This, in turn, influences both battery safety and performance. So it is crucial to know the effects of temperature on lithium ion batteries.

What Is The Ideal Temperature for Lithium Batteries?

To ensure optimal performance, it is recommended to keep lithium ion batteries in cool and dry environments. The acceptable temperature range for these batteries typically falls between 5°C and 20°C. Extremely cold temperatures, like 0°C, can lead to capacity loss as the battery’s chemical reactions slow down due to the low temperature. Excessively high temperatures can pose risks such as fire and explosion.

What Are The Potential Hazards Linked to Extreme Storage Temperatures?

The storage temperature of lithium ion batteries directly impacts the chemical reactions occurring within the battery cells.

Extremely low temperatures can lead to a decrease in the energy and power capacity of lithium ion batteries. Elevated ambient temperatures can cause the internal temperature of the battery to rise, also resulting in decreased performance and power capabilities.

Moreover, high ambient temperatures pose additional risks. If the temperature surpasses a critical threshold, it can trigger thermal runaway in the lithium ion batteries.

How to Reduce Risk?


Before storing your lithium ion batteries, it is important to ensure that they are at the recommended state of charge (SOC). It is generally advised to store lithium ion batteries at around 40% SOC for optimal performance. Failing to store your batteries at this level may lead to cell instability.

Storage Environment 

To properly store lithium ion batteries, it is crucial to place them in a cool, dry, and well-ventilated environment, away from direct sunlight and any sources of heat or ignition. It is essential to maintain a consistently stable temperature in the storage area, ideally ranging between 5 to 20°C.


Temperature has an impact on the functioning of lithium ion batteries. It is possible to encounter low-temperature conditions while using these batteries. To ensure the best possible battery performance in such situations, Polinovel has designed a preheating system on the Battery Management System that enables charging at temperatures as low as -40℃. If you live in high-latitude regions or partake in winter activities like ice fishing, these self-heating lithium batteries are an ideal choice to fulfill your requirements.
