Safety
Sodium-ion battery fire risk
Sodium-ion may lower some thermal-runaway risks, but a complete battery can still burn, release hazardous gases or create an electrical fault.
What matters
Cell materials influence heat release and propagation. Organic electrolyte remains combustible in many designs. Pack energy, spacing, enclosure, detection and isolation determine how a fault develops.
The detail
Manufacturer videos and single abuse tests do not establish universal safety. Look for standards, independent certification, installation requirements and a fault-management design for the exact system.
Practical conclusion
Keep the emergency shutdown instructions accessible and tell household members where isolation is. In a fire, leave the area and call 999; do not improvise firefighting advice from a chemistry label.
