Battery Diagram with Components

Here's a straightforward diagram presenting the internal layout of a standard cylindrical battery. You can clearly see the central carbon rod, which functions as the positive current collector. This rod is surrounded by the cathode mixture, typically a blend of manganese dioxide and carbon, alongside the electrolyte. The outer layer is a metal casing, often steel, which serves as the negative terminal. The diagram also illustrates the sealing mechanisms at the top and bottom, and an outer wrapper, providing a helpful look at how these common power sources are put together.
