What happens to lithium-ion batteries when exposed to acid?

• A. will contaminate the battery and damage it, making it inoperable
• B. will recharge the battery
• C. improves battery efficiency
• D. has no effect on the battery

Answer: (A)

Exposure to acid disrupts lithium-ion battery chemistry by creating a corrosive environment inside the cell. The electrolyte in most Li‑ion batteries is a lithium salt dissolved in an organic solvent, and acid can react with this electrolyte as well as with electrode materials. This leads to contamination, decomposition of the electrolyte, gas formation, and corrosion of metal components such as current collectors and separators. The resulting damage interferes with ion transport and electrical connections, often causing internal short circuits, loss of capacity, increased impedance, and, in many cases, rendering the battery inoperable. Acid exposure does not recharge the battery, nor does it improve efficiency, and it clearly has a detrimental effect.
