Which scenario would cause a lithium-ion battery to become inoperable?

Which scenario would cause a lithium-ion battery to become inoperable?

• A. Exposure to acid
• B. Exposure to heat but no acid
• C. Regular charging
• D. Proper storage

Answer: (A)

Exposure to acid would cause chemical reactions inside a lithium-ion cell that attack the electrolyte and electrode materials, potentially leading to leakage, corrosion, internal short circuits, and loss of internal structure. Once the electrolyte and interfaces are damaged, the battery can no longer operate correctly. Heat alone can accelerate aging or cause failure if extreme, but it isn’t inherently guaranteed to make the cell inoperable the way acid exposure can. Regular charging and proper storage are normal, safe practices that help maintain functionality.
