What stores and converts electrochemical energy?

What stores and converts electrochemical energy?

• A. Battery
• B. Conductor
• C. Capacitor
• D. Inverter

Answer: (A)

A battery stores chemical energy and converts it to electrical energy. Inside, chemical reactions between the electrodes and electrolytes store energy in chemical bonds. When the circuit is used, those reactions release energy, producing an electrical current and thus converting chemical energy into electrical energy. Charging reverses the reactions, restoring stored chemical energy. A conductor just provides a path for electrons and does not store or convert energy. A capacitor stores energy as an electric field between plates, which is electrical energy stored electrostatically, not chemical. An inverter changes the form of electrical energy (for example, DC to AC) but does not itself store chemical energy.
