SECTION 10. STABILITY AND REACTIVITY
10.1 Reactivity
None during normal handling and use.
10.2 Chemical stability
Stable under normal conditions.
10.3 Possibility of hazardous reactions
Severe mechanical or electrical damages of the battery can cause the failure of the battery with the emission of potentially corrosive and/or toxic substances for inhalation, ingestion and contact with the skin and can cause the generation of flammable gas and eventually fire without explosion.
If the external metallic boxes and cells are damaged, liquid electrolytes will leak out and cause a short circuit between other cells leading to successive battery cell destruction and overheating.
Cells are designed so that any severe distortion of the cell case will first break the internal ceramic insulator: free metallic sodium within the cell case reacts with other constituents forming sodium chloride and aluminium; this reaction greatly minimises the possibility of free metallic sodium leakages.
10.4 Conditions to avoid
AVOID contact of the items with water according to IP 55 rating of the battery.
10.5 Hazardous decomposition products
Formation of toxic gases is possible in case of fire.
