Lead is widely used in the construction of batteries, particularly in lead-acid batteries, which are essential for vehicles, uninterruptible power supplies, and renewable energy storage systems. Its ability to resist corrosion and conduct electricity makes it a key component in these applications. Additionally, lead is utilized in radiation shielding, such as in X-ray rooms and nuclear reactors, due to its high density and effectiveness in blocking harmful radiation. In the past, lead was commonly used in paints and plumbing, but its use has significantly declined due to health and environmental concerns. It is also employed in the production of certain alloys, like solder and bearings, to enhance durability and performance. Despite its versatility, strict regulations now govern its use to minimize exposure and environmental impact.
