Which statement describes Nickel Cadmium batteries?

Which statement describes Nickel Cadmium batteries?

• A. Nickel Cadmium - Rechargeable alkaline base
• B. Lead Acid - Sealed battery
• C. Lithium - High energy density storage
• D. Non-rechargeable battery

Answer: (A)

Nickel-Cadmium batteries are rechargeable cells that use an alkaline electrolyte. The positive electrode is nickel oxide hydroxide and the negative electrode is cadmium, with the electrolyte typically being potassium hydroxide. This combination gives them the ability to be charged and discharged many times and to perform well over a wide temperature range, which is why they’re described as rechargeable alkaline batteries. The other options point to different chemistries (lead-acid, lithium) or to non-rechargeable cells, which don’t describe NiCd.
