Is it bad to store lithium batteries fully charged?
Key Takeaways
- Storing lithium batteries fully charged can lead to increased stress on the electrodes, accelerated degradation of the electrolyte and electrode materials, and faster overall degradation of the batteries.
- Keeping lithium batteries at around 40-50% State of Charge (SoC) is recommended to be ready for immediate use and to prevent overcharging, which can damage the battery.
- Over discharging lithium batteries can cause irreversible damage and decrease their capacity and performance. It is recommended to keep them between 20% and 80% charged whenever possible.
Storing lithium batteries fully charged has been a point of discussion among battery enthusiasts and experts. Some argue that it can lead to increased stress on the electrodes, accelerated degradation of the electrolyte and electrode materials, and faster overall degradation of the batteries. Others claim that fully charging lithium batteries is not detrimental and that they prefer to be kept at higher charge levels. So, what is the truth behind storing lithium batteries fully charged? Let’s delve into the details to find out.
Effects of Storing Lithium Batteries Fully Charged
According to Redway Tech, storing lithium batteries fully charged can lead to increased stress on the electrodes, accelerated degradation of the electrolyte and electrode materials, and faster overall degradation of the batteries. Overcharging can also cause increased temperature and potential damage or leakage of the battery. This suggests that keeping lithium batteries at full charge for extended periods may not be ideal for their longevity.
Similarly, Battery Guy recommends keeping lithium batteries at around 40-50% State of Charge (SoC) to be ready for immediate use. Fully charged lithium batteries can reduce their recoverable capacity over time and may be more prone to overcharging, which can damage the battery.
On the other hand, Redway Battery claims that keeping lithium batteries fully charged for extended periods does not lead to overcharging or reduce their lifespan. In fact, they argue that lithium batteries prefer to be kept at higher charge levels. However, the real risk associated with lithium batteries is over discharging, which can cause irreversible damage and decrease their capacity and performance. They recommend keeping lithium batteries between 20% and 80% charged whenever possible to maintain their health and longevity.
The information provided by Popular Science does not specifically address the risks of storing lithium batteries fully charged.
Best Practices for Storing Lithium Batteries
While the effects of storing lithium batteries fully charged may be subject to debate, there are some general best practices for safely storing lithium batteries, as outlined by Storables:
- Location: Choose a cool and dry location for storing lithium batteries. High temperatures can accelerate the degradation process and increase the risk of thermal runaway.
- Packaging: Store lithium batteries in their original packaging or use specialized battery storage containers. This helps protect them from physical damage and prevents contact with other metal objects that could cause a short circuit.
- Temperature Control: Avoid exposing lithium batteries to extreme temperatures. Store them within the manufacturer’s recommended temperature range to maintain their optimal performance and prevent potential hazards.
- Ventilation: Ensure that the storage area is well-ventilated to prevent the accumulation of flammable gases that may be released by damaged or overheated batteries.
- Insulation: Store lithium batteries away from flammable materials and ensure they are properly insulated to minimize the risk of fire in case of thermal runaway.
- Avoid Moisture: Keep lithium batteries away from high humidity or moisture, as it can damage the battery’s internal components and reduce its overall capacity.
- Follow Manufacturer Guidelines: Always follow the manufacturer’s instructions and guidelines for safe storage and handling of lithium batteries. They may provide specific recommendations based on the type and model of the battery.
Conclusion
Based on the available information, it is evident that storing lithium batteries fully charged can have negative effects on their longevity and overall performance. While there may be differing opinions on the matter, it is generally recommended to keep lithium batteries at around 40% – 60% state-of-charge for optimal longevity. This range helps balance the need for immediate use and the potential risks associated with overcharging and accelerated degradation.
