Primary battery: Primary batteries are irreversible transform chemical energy to electrical energy. When the initial supply of reactants is exhausted, energy cannot be readily restored to the battery by electrical means.
Secondary battery: This can be recharged, that is they can have their

Concept introduction:
Electrochemical cell is a device capable of converting chemical energy into electrical energy or induces chemical energy by electrical energy. In the galvanic cell spontaneous redox reaction takes place. Redox reaction means the reaction in which the oxidation state of the atoms changes due to the occurrence of both reduction and its complementary oxidation reactions. The element under oxidation reaction loses electron whereas the element in the reduction gains electron.
Primary battery: Primary batteries are irreversible transform chemical energy to electrical energy. When the initial supply of reactants is exhausted, energy cannot be readily restored to the battery by electrical means.
Secondary battery: This can be recharged, that is they can have their chemical reaction reversed by supplying electrical energy to the cell restoring their original composition.
(c)
Interpretation:
Household battery recycling programs have not been as effective as those for recycling car batteries and list some reasons should be provided.
