What are Lithium-ion Batteries?

Since their introduction in 1991, lithium-ion (Li-ion) batteries remain popular among small and large corporations alike due to their long lifespans and lightweight designs. Today we use them as the main power source for smartphones, laptops, tablets, military drones, and even electric cars. However, if lithium batteries are not stored properly, they can be extremely dangerous. In this article, we’ll offer some suggestions on how to store lithium batteries.

Tips for Lithium-ion Battery Storage: Temperature and Charge

Temperature is vital for understanding how to store lithium batteries. The recommended storage temperature for most is 59° F (15° C)—but that’s not the case across the board. So, before storing lithium batteries, thoroughly read labels on proper storage for your specific battery type. Lithium battery storage buildings with climate control are ideal for storing bulk quantities of Li-ion batteries at specific temperatures to ensure a safe storage environment.

Also, be aware of the state of charge while storing. Always keep lead acid at full charge during storage. Nickel and lithium-ion batteries should be stored at around 40% state of charge. If improper storage occurs, lithium-ion batteries might become unstable. This may cause excessive heat to damage it internally and potentially catch on fire. Store cells with a charge between 30% and 50%. The cells can be stored fully discharged, although the cell voltage should not drop below 2.0 for optimal safety. The maximum voltage should not exceed 4.1 volts. Always follow the charging instructions provided with each Li-ion battery.

How to Store Lithium-ion Batteries: Maintenance and Handling Precautions

  • Monitor battery charge status while charging
  • Ensure temperature controls are set to specified temperatures
  • Observe run time with a fully-charged battery
  • Ensure batteries self-discharge
  • Check batteries before placing them in storage for irregularities in charge status
  • Avoid exposing Li-Ion batteries to excessive vibration
  • Do not keep batteries in high or low temperatures
  • Always handle batteries with caution
  • Place batteries in storage after the building reaches compliant temperature levels
  • Do not use damaged batteries
  • In case of contact with fluid do not rub eyes. Immediately flush eyes at an eyewash station
  • Wash hands after handling batteries
  • In the event of contact on clothing, change clothing immediately

The Best Place to Store Batteries

Lithium battery storage buildings are 100% customizable and can be equipped with charging stations for safe convenience.

Our Battery Storage Solutions

Temperature is a vital factor in ensuring your batteries are stored safely, which is why we offer climate control options for your storage building, including accessible controls and a thermostat to keep your operation running smoothly.

Fire suppression systems are a must for storing hazardous materials, which is why we offer several options for fire suppression, including dry chemical storage fire suppression, water sprinklers, and fire extinguishers for peace of mind.

Our buildings also feature mechanical ventilation, fiberglass grated flooring, and a variety of door styles for exit and entry. These factors are designed with the user in mind for the safe movement of lithium-ion batteries. Being able to access your materials when and where you need them is crucial to smooth, productive operation.

Location is another critical aspect of storing batteries long term. U.S. Chemical Storage provides safe, reliable, prefabricated storage buildings, including solutions for outdoor and indoor storage. Non-fire rated designs offer a place for lithium-ion batteries to be stored outside of facilities, while fire-rated lithium storage buildings can be located near or inside of facilities for boosted productivity and efficient manufacturing operations.

Keep your lithium-ion batteries easily sectioned with multi-room storage.

    1. Elevated temperature generally hastens permanent capacity loss in Li-ion batteries. We recommend they be stored in a cool, dry location (like our pre-fabricated storage buildings) with AC and temperature controls to store them at around 15-degrees Celsius for the ideal performance. We strongly recommend you reach out to the battery’s manufacturer for specifics for your specific type of Li-ion battery’s limitations.

  1. Assuming dry and cool warehouse area for storage – does it makes any difference if Li-ion batteries are stored tightly packed together or do they need space? Any difference if stored inside plastic crates vs wooden crates?

    1. Storing in plastic or wooden crates is not recommended, since they are not fire-rated and lithium is considered a flammable. We will have a technical sales engineer reach out to you to learn more about your specific questions and application with these types of batteries.
