The plates in a car battery are typically made of lead and are often coated with a black substance, usually a lead oxide. This black coating helps to enhance the battery's efficiency by increasing the surface area for the chemical reactions that produce electricity. Additionally, the black color can help dissipate heat more effectively, contributing to better performance and longevity of the battery.
