Question

Write the name of the cell which is generally used in inverters. Write the reactions taking place at the anode and cathode of this cell, when it is in use.

Hint:

Lead-acid batteries are commonly used for energy storage and backup in inverters due to their reliability and cost-effectiveness.

Answer 1

The cell generally used in inverters is a Lead-acid battery. The reactions occurring at the anode and cathode during the discharge are as follows: At the anode (oxidation): \[ \text{Pb(s)} + \text{SO}_4^{2-} \longrightarrow \text{PbSO}_4(s) + 2e^- \] At the cathode (reduction): \[ \text{PbO}_2(s) + \text{SO}_4^{2-} + 4e^- \longrightarrow \text{PbSO}_4(s) + 2H_2O \] Thus, the overall reaction is: \[ \text{Pb(s)} + \text{PbO}_2(s) + 2\text{H}_2\text{SO}_4 \longrightarrow 2\text{PbSO}_4(s) + 2H_2O \] The lead-acid battery is widely used in inverters due to its high energy density and ability to deliver high current.
