Lithium-Ion Battery Safe
This an article describes how to make your own LiIon Battery Safe storage box.
LiIon battery fires are really getting in the news lately. http://tinyurl.com/wkbfztyp
This nearby incident recently caused a fire in a two-story apartment building. The cause was a LiIon Scooter in a closet.
I have seen a few of these batteries short out during abnormal charging.
They are not known for exploding in storage conditions, but there is a lot of potential energy in them. Backpackers love them because they have twice the energy and half the weight of a NiCad battery.
Most people use them in cordwood stacks and if one explodes in a stack, it will take the rest of them with it, one at a time. It is like an ammunition “Cook Off” test. They are like a type “F” Estes Rocket Motors. You can’t extinguish them with your kitchen fire extinguisher. All your smoke alarms will start going off and your room will quickly fill with smoke. It is not nice.
It is best to never charge a big battery without monitoring the charge and using a LiIon Battery Safety Shutdown system.

It is a good idea to have a handle on your battery to be able to lift the exploding battery outside as soon as possible.
I built my Storage Box in a 3-foot-high cabinet (19-inch rack). It also has wheels and I keep it outside and 30 feet away from any buildings. The batteries are in metal cases and then placed in Ammo cans. These cans are then stored inside the Safe. It has about 100 - 26650 cells in it.
The typical LiIon battery has good environmental storage specifications. Mine are rated at -20C to +45C. They won’t be damaged being passively stored outside. These are storage temperatures not charging temperatures.

| One more thing for LiIon battery safety, keep LiIon batteries and any device that contains LiIon batteries away from dogs that have a penchant for chewing things. https://internationalfireandsafetyjournal.com/dog-chews-lithium-ion-battery-sparking-house-fire-in-tulsa/ Video at: https://www.cnn.com/2024/08/07/us/video/lithium-battery-fire-dog-tulsa-cprog-digvid | ||

| What I don't understand, is why would one want to store so many batteries that they're this fearful to keep around? If I needed this many batteries on-hand, I'd send the Li-Ion cells to the recycling depot and convert everything to LiFePO4 chemistry; problem solved. Keeping this many Li-Ion cells massed together in one place is ludicrous. | ||

| The main thing is to store them at least 10ft from your house. If Li-Ion batteries cook off the heat is sufficient to melt through the Ammo Box and cabinet. Stainless steel might be the only thing other than Ceramics that will contain it. Trying to contain it is just too expensive. The main thing is to keep it away from house and any flammable material is may use to spread to your house. | ||
