Many of the components in ___ batteries are recyclable.

• A. Nickel-metal hydride batteries
• B. Lead-acid batteries
• C. Lithium-ion batteries
• D. Fuel cell

Answer: (C)

Recyclability in batteries comes from the materials used and the recycling methods available to recover those materials. In lithium‑ion batteries, many of the components—metals like lithium, cobalt, nickel, aluminum, copper, plus the plastics and separators—can be recovered and reused through established recycling processes. This makes a large portion of the battery’s contents recyclable, supporting material conservation and reducing environmental impact as recycling programs continue to grow. A fuel cell isn’t a battery, so it doesn’t fit the prompt. Nickel‑metal hydride batteries do contain recyclable metals, but the current recycling infrastructure and material mix in practice are most strongly associated with lithium‑ion batteries.
