Which battery type is primarily non-rechargeable and uses the lithium metal or compounds as the anode?

• A. Lithium Ion Batteries
• B. Lithium Battery
• C. Lithium Battery
• D. Lithium Metal Batteries

Answer: (D)

Lithium metal batteries are non-rechargeable and use lithium metal as the anode, which is what defines this type. Because the anode is lithium metal, the chemical reactions during discharge are not easily reversed, so these cells are designed as primary (single-use) batteries. In contrast, lithium-ion batteries are rechargeable and rely on lithium ions moving between materials, with anodes like graphite rather than lithium metal, so they’re a different family of chemistries. The term lithium battery can be ambiguous, but when the description specifies a non-rechargeable cell with a lithium metal anode, the correct term is lithium metal batteries.
