-
Reduced capacity: Cold temperatures can limit the chemical reactions within the battery. At typical freezing temperatures (around 0°C or 32°F), lithium-ion batteries can lose as much as 20-30% of their capacity. A study by Wang et al. (2019) found that performance drops significantly during cold weather, affecting the total energy available for use.
-
Increased internal resistance: Low temperatures lead to higher internal resistance in lithium batteries. This means that more energy is needed to push the current through the battery. According to a paper by Zhang et al. (2020), this increased resistance results in reduced efficiency and may lead to overheating during charging, which can damage the battery.
-
Shortened lifespan: Prolonged exposure to cold can also impact the lifespan of lithium batteries. The crystallization of lithium salts at low temperatures can cause dendrites to form, which can puncture the separator within the battery and result in short circuits. A study by Yang et al. (2021) indicated that repeated cycling of lithium batteries at low temperatures can reduce their lifecycle by as much as 50%.
Overall, the negative effects of cold temperatures on lithium battery performance can hinder their capacity to function effectively, maintain efficiency, and prolong lifespan, making it essential to store them properly in colder conditions.

How Can You Prepare Lithium Batteries for Cold Weather Storage to Ensure Longevity?
To prepare lithium batteries for cold weather storage and ensure their longevity, follow these key steps: charge the batteries to around 50%, store them in a cool, dry place, and check them periodically.
Charging to 50%: Lithium batteries should be charged to approximately 50% of their capacity before storage. This level helps maintain the battery’s health during long periods of inactivity. Keeping the battery too full can increase the risk of capacity loss due to stress, while a very low charge can lead to a state of deep discharge, which can permanently damage the battery. A study by Plett et al. (2015) found that lithium-ion batteries experience a degradation rate of up to 20% when stored at a charge below 30% for extended periods.
Storing in a cool, dry place: The ideal storage temperature for lithium batteries is between 32°F (0°C) and 68°F (20°C). Cold temperatures can reduce the battery’s performance but prevent chemical reactions that can lead to degradation. High humidity can also negatively affect the battery’s materials, leading to corrosion. As noted in research by Wang and West (2016), storing batteries in optimal conditions can significantly extend their lifespan, reducing the risk of rapid capacity loss and swelling.
Periodic checks: It is essential to check the batteries every few months during storage. This practice helps ensure that they are not discharging too much and that no physical damage has occurred. If the batteries discharge below 30%, recharge them to the 50% level again. Regular maintenance can be critical; according to the Journal of Power Sources, batteries that are monitored during storage maintained 60% of their initial capacity after one year compared to only 30% for those neglected (Zhang et al., 2017).
By following these steps, it is possible to enhance the performance and lifespan of lithium batteries during cold weather storage.
