Question

4. a) What are batteries? Explain the working of Ni-Cd battery.

Answer 1

Explanation:

The Nickel Cadmium Battery is rechargeable, so it can cycle repeatedly. A nickel cadmium battery converts chemical energy to electrical energy upon discharge and converts electrical energy back to chemical energy upon recharge. ... In the anode, cadmium hydroxide is transformed to cadmium.

Answer 2

$A nickel cadmium battery converts chemical energy to electrical energy upon discharge and converts electrical energy back to chemical energy upon recharge. In a fully discharged NiCd battery, the cathode contains nickel hydroxide [Ni(OH)2] and cadmium hydroxide [Cd(OH)2] in the anode.✌️$
