The electrolytes in lithium-ion batteries are what?

• A. Non-conductive
• B. Flammable
• C. Cryogenic
• D. Non-flammable

Answer: (B)

Lithium-ion battery electrolytes are flammable liquids that conduct lithium ions between the electrodes. They’re not non-conductive, because ion transport is essential for charging and discharging. They’re not cryogenic, since they’re designed to work at room temperatures and can ignite when heated. The typical electrolyte consists of organic solvents with dissolved lithium salt, which provide the necessary ion flow but can burn if exposed to heat, a spark, or a puncture. This is why thermal management and protection against short circuits are important safety considerations.
