Which one among the following is an electrochemical cell that cannot be charged?

Electrochemical cells are categorized based on their reusability. A primary cell is a single-use electrochemical device that cannot be recharged once its chemical reactants are exhausted. In these cells, the electrochemical reaction is irreversible, meaning the electrode material and electrolyte degrade during discharge and cannot be restored by an external power source [1]. Common examples include zinc-carbon dry cells and alkaline batteries used in flashlights [1]. In contrast, storage cells (secondary cells) are designed to be recharged by reversing the chemical reaction with an external current. Fuel cells differ as they are continuous energy converters that require a constant external supply of fuel, such as hydrogen, to generate electricity [1]. Electrolytic cells are devices that use electrical energy to drive non-spontaneous chemical reactions [2].
