Here is a quick guide to storing lithium batteries, answering common questions, and a safety checklist to ensure proper storage and the best performance, and durability for any user.
Why Proper Lithium Battery Storage Matters
Proper storage of lithium batteries is essential for anyone who owns any equipment, devices, electric appliances, or even electric vehicles that use lithium-ion batteries in themselves. A significant number of damages may occur if the battery is not stored appropriately. That is why we need to understand the nature of lithium-ion batteries, along with its storage conditions so that we can prevent any harmful situations caused by such batteries
One of the risks associated with lithium-ion batteries is that it gets overheated and can catch fire at any point when kept in unsuitable conditions such as extremely high temperatures. When batteries are stored at a temperature higher than 60C, they undergo thermal degradation. As a result of this, batteries can experience a decrease in their life span and have a fire hazard.
Another inherited risk of lithium batteries is that their shelf life is limited. This means lithium batteries gradually lose their strength over time. Even in case the battery is not in use, it loses its efficiency. Plus, external temperature plays a big role in its depletion and inefficiency. The higher the temperature, the more the speed of depletion of lithium batteries is.
Over-exposure to heat can worsen the battery’s working atmosphere. For instance, if batteries are stored in a hot garage or are left under sunlight all the time, the efficiency of the battery is greatly reduced. On the other hand, keeping lithium batteries under extreme cold temperatures is also harmful to the batteries as it temporarily suspends its functioning. Thus, extreme hot or cold temperature changes during its storage period can cause malfunctioning of all the electronic devices that use these batteries.
Moreover, any physical damage to the battery casing and the internal battery components can be prevented if batteries are stored properly. If there is a battery casing dented or punctured, it will most likely cause a thermal runaway. The delicate balance to store lithium batteries is vital to make them reliable, reducing the chances of such accidents. By paying extra careful attention to storage, the life span of lithium batteries can be extended drastically.
Key Principles of Lithium Battery Storage
Lithium battery storage principles are very important to secure the safety and longevity of the lithium battery. The principles are to minimize the risk of the environment, minimize the hazards of the batteries, and keep the performance level of the battery constant. The process of principle should start with the right area, then a decent container, and lastly, stored in not crowded space.
The first step to store batteries is to pick an appropriate location. This step will decrease the level of extreme environments or the risk of exposure to extreme environments. Normally, batteries must be stored in a dry, cool, and well-ventilated place. If the air is too humid, then it can lead to corrosion of the battery terminals. On the contrary, if the air has zero humidity, then the battery outer casing may dry and become extremely brittle.
Never stock batteries in places that will become too hot or too cold. A battery that is too hot can suffer irreparable damage internally. Temperatures over 60°C can damage internal components and promote thermal runaway. It is recommended to store batteries between 15°C to 25°C, also known as the lithium battery storage temperature. Moreover, batteries should be kept in a safe place, protected from heat sources, and out of direct sunlight. The ideal place to store batteries would be a cool, dry climate control room or basement.
When storing the batteries, the selection of the storage container also is very important. It is important to never congest the storage space inside any tight container. Space should be wide enough for the battery to be easily isolated from one another. This ensures that there is proper ventilation and the overflow of heat is most unexpected. Also, it is essential to avoid the physical contact of individual batteries. This is because the contact of the cells may lead to an accidental short-circuit. Stacking or cramming the batteries increases the possibility of damaging their casings, ultimately leaking and failing. Overcrowded conditions can induce high temperatures and is generally unsafe and hazardous.
A fire-resistant type of container is highly recommended for storing batteries. If you stock plenty of batteries in the storage place, then it is good to use a store in fireproof containers. These containers are heat insulators and do not allow the heat exits and cause ignition.
Regular plastic or metal containers may seem convenient, but they pose certain risks. Plastic is flammable, and metal is a conductor of heat. Therefore, these normal boxes should often be replaced by a more durable and safe version due to the safety of the user.
The right storage solution depends on the combination of durability and safety. Using a special fire-resistant lithium-ion battery container or a durable battery cabinet is an essential safety step, especially for a home or facility with bulk battery storage needs.
A majority of people never take battery storage seriously. Once you understand lithium battery storage principles or storage procedures mentioned above, it’s simple. By following a few specific lithium battery storage methods, the risk of any incorrect handling can considerably be reduced. Selecting the right location to store, using fire-resistant storage methods, and not crowd the batteries are very critical steps that can ensure your batteries are safe, functional, and available. These practices are the fundamental to responsible energy storage circumstances.
Long-Term Storage Tips for Lithium Batteries
When it comes to storing lithium batteries for an extended period, one has to be mindful of the different ways to maintain its functionality. The tips to do so are by keeping the right level of charge, periodic checking and controlling temperature. By following these tips, the person can store lithium batteries for a longer period.
-
Charge level to be maintained:
The primary rule regarding the Li-ion battery long-term storage is to store it with a partial charge (40-60 percent). Lithium-ion batteries are very sensitive to overcharging and deep discharging. It is proven to affect the life of the batteries. A fully charged battery when stored for a long time will increase its stressed status and thereby reducing the lifespan. If one stores the battery in a deep discharge state, it might not charge, and it slips into a deep discharge state. No matter if they’re small consumer batteries or larger units, this principle of storing lithium-ion batteries remains the same.
-
Periodic checking:
One should periodically inspect a stored lithium battery at home to check for any signs of damage, swelling, leakage, corrosion, etc. Batteries may experience self-discharge if left unused and unmonitored for too long, which might result in the over-discharge state. This is the state in which the battery usually prevents a recharge. It is best practice to check your batteries every three to six months and charge them up to their optimal storage level if necessary.
-
Temperature Control:
It’s important to any particular lithium battery’s specifications, particularly regarding temperature control, during the period it’s stored. Different lithium-ion batteries have optimal storage temperatures, which are mentioned in the batteries’s labels.
With these instructions, you’ve combined a complete guide on how to store lithium batteries safely. A stable room temperature that falls within the recommended lithium-ion battery storage temperature range is favorable over both hot and cold weather. This way, batteries can neither freeze during winter nor overheat in summer, ensuring their chemical integrity is conserved and prolonged. Therefore, to achieve stable lithium battery preservation, maintain a partial charge, conduct daily checks, and prevent storing batteries in extreme weather.
Safety Concerns and Precautions While Storing Lithium Batteries
Storing lithium batteries safely is essential to prevent accidents and hazardous situations. By knowing the specific hazards involved in storing lithium batteries and taking necessary precautions, we can greatly reduce these risks.
The primary concern when it comes to storing lithium batteries is overheating. If lithium-ion batteries are exposed to an extreme temperature, damaged physically, or not appropriately charged, the lithium-ion battery would explode or catch fire. When a lithium-ion battery experiences overheating, a process called thermal runaway occurs, which increases internal temperatures rapidly, causing a fire or an explosion. So, to avoid this heat buildup, the batteries must be stored in a dry, cool, and aerated area. It should also be far from any flammable materials so that if something goes wrong, only a small accidental fire or explosion is caused.
To ensure that there is no risk in storing lithium batteries and that the battery is safe in both short and long-term storage is to learn the proper way to store a lithium battery.
Another crucial thing to worry about is dealing with damaged or swollen batteries. A lithium battery showing any physical damage or swelling must never be used. Can you use a damaged lithium battery? No. Overheating in batteries can cause severe damage such as swelling, leakage, or physical damage. When a battery starts swelling, it causes severe risks of the battery catching fire. A damaged battery of such sort can also explode. In case of such an incident, the accidentally damaged battery must be removed from any devices and can be stored safely in a fireproof container or a battery cabinet.
Disposal of damaged or expired batteries should be followed according to the regulations provided by the battery manufacturers. If you dispose of the battery with less care, it may become an environmental hazard or fire risk.
Finally, when you keep the lithium batteries in a vehicle or an outdoor area, it’s the utmost priority to be careful. Keeping an e-bike battery in a hot garage or an external battery in a hot car, the battery gets exposed to extreme temperatures. The internal features of a battery will most likely have irreversible damage to it due to high heat. In particular, the battery’s capacity lessens with high heat; in the worst conditions, leaks and fires can occur.
The batteries should not be left in places with direct sunlight falling on them or heat. Due to storing batteries in such conditions the life span of the batteries gets reduced and may give danger to the individuals.
Common Myths and Misconceptions About Lithium Battery Storage
For storing lithium batteries, numerous myths and misconceptions may often lead to inappropriate practices, which in turn can damage the batteries or reduce their life span. It is important to address and debunk these myths using proper information so that the batteries may be stored safely and perform well. So in this section of the article, we will answer questions and beliefs such as; whether batteries last longer in the refrigerator, whether we should keep batteries in the refrigerator, or whether lithium batteries last indefinitely without care.
One of the most popular myths is to store the batteries in the refrigerator or freezer to boost performance and increase the service life. Many people believe that by storing the battery in cold temperatures, the degradation of the battery can be reduced. However, this is not the case for lithium-ion batteries. Many people believe in storing batteries in the refrigerator because they feel that do batteries last longer in the refrigerator. However, this assumption is wrong. Refrigerators can introduce moisture into the casing of the battery, which when condensed can damage internal parts. Another reason why you should not keep batteries in the refrigerator is that extreme cold can cause the electrolyte in the battery to thicken, which can influence the correct charge and discharge rate of the battery. Hence refrigerators are not a suitable place to store the batteries. Instead, lithium batteries are best stored at a consistent room temperature, in a dry and cool place to ensure safety and a longer life span.
Another popular myth is lithium batteries last indefinitely without care. This particular myth makes you believe that the batteries last fairly long without any care. This misconception about lithium batteries is very harmful and dangerous because that encourages you to neglect to the battery health over time.
Although one might think about how long batteries last in storage. The answer to that specific question is, that there is a time limit. While lithium batteries which are entirely charged may last for quite a lot of months. But the battery deteriorates and the state of the battery worsens with time, being stored without usage. The lithium battery shelf life and the lithium battery operating temperature are crucial factors in deciding how long the battery retains charge and performance. When stored at high or low temperatures, they can lose their life expectancy to a significant extent. Storing lithium batteries also comes as a responsibility, and they need to be stored at about 40-60% charge at room temperature. This prevents over-discharge or excess charge and can influence their capacity and safety.
So store lithium batteries comes in a fridge or freezer, and refrigerating or freezing lithium batteries isn’t recommended. Lithium batteries that last beyond their shelf life can be misleading. It is found to be critical to maximize the battery lifespan and safely store and use them.
