Sodium-ion electrolytes explained
Most current sodium-ion cells use a sodium salt dissolved in organic solvents, not table salt in water.
What matters
The electrolyte must conduct Na⁺ across the temperature range while remaining stable at both electrodes. Additives help create protective interphases and reduce gas or degradation.
The detail
Organic solvents may be flammable. Research into aqueous, solid and alternative electrolytes aims to change safety or cost, but those labels describe different cell systems.
Practical conclusion
Do not infer non-flammability from the word sodium. Use the product safety data and certification for the exact cell and pack.
