Special hazard: Cells may explode and release metal parts.
At contact of electrolyte with water traces of hydrofluoric acid may be formed.
In this case avoid contact and take care for good ventilation.
At contact of charged anode material with water extremely flammable
hydrogen gas is generated.
Attention: Do not let used extinguishing media penetrate into surface water or ground
water. If necessary, thicken water or foam with suitable solids. Dispose off
properly.
6. Accidental release measures
Person related measures: Wear personal protective equipment adapted to the situation (protection gloves,
face protection, breathing protection).
Environment protection measures: Bind released ingredients with powder (rock salt, sand).
Dispose off according to the local law and rules.
Avoid leached substances to penetrate into the earth, canalization or water.
Treatment for cleaning: If battery casing is dismantled, small amounts of electrolyte may leak. Package
the battery tightly including ingredients together with lime, sand or rock salt. Then
clean with water.
7. Handling and storage
Guideline for safe handling:
Always follow the warning information on the batteries and in the manuals of
devices. Only use the recommended battery types.
Keep batteries away from children.
For devices to be used by children, the battery casing should be protected
against unauthorized access.
Unpacked batteries shall not lie about in bulk.
In case of battery change always replace all batteries by new ones of identical
type and brand.
Do not swallow batteries.
Do not throw batteries into water.
Do not throw batteries into fire.
Avoid deep discharge.
Do not short-circuit batteries
Use recommended charging time and current.
Storage:
Storage preferably at room temperature (approx. 20°C). Avoid large
temperature changes. Do not store close to heating devices. Avoid direct
sunlight. At higher temperature the electrical performance may be reduced.
Preferred storage at 50% of the nominal capacity (OCV 3.7 – 3.9V or multiples
of this in case of serial multi-cell configurations).
Storage of unpacked batteries can cause short circuit and heat generation.
Storage of large amounts:
If possible, store the batteries in original packaging (because of short circuit
protection and exemptions according to transport regulations).
A fire alarm is recommended.
For automatic fire extinction consider chapter 5 “Fire fighting measures”.
VCI storage category:
It is recommended to consider the “VCI Guideline for the mixed storage of
chemicals” and to handle lithium ion batteries according to storage category 11
(“combustible solids“).
