What is the term for a single storage unit of chemical energy in a battery?

• A. Cell
• B. Battery
• C. Capacitor
• D. Anode

Answer: (A)

A single storage unit of chemical energy in a battery is a cell. Each cell contains the chemical reactions that store and release energy as it operates. When multiple cells are connected together, they form a battery with higher voltage or capacity. A capacitor stores energy in an electric field, not chemically, so it’s not the correct term here. An anode is one electrode within the cell where oxidation occurs, not the energy-storage unit itself.
