Cadmium is a soft, bluish-white metal primarily used in batteries, particularly nickel-cadmium (NiCd) batteries, as well as in coatings, pigments, and stabilizers for plastics. Its economic significance lies in its role in renewable energy technologies and electronics, although environmental concerns have led to increased regulation and reduced usage in some applications.
