These dry cells are also referred to as Leclanche' cells. The internal parts of the cell are loed in a cylindrical zinc container. This zinc container serves as the negative electrode (hode) of the cell. The container is lined with a nonconducting material, such as blotting paper, to separate the zinc from the paste. A carbon electrode is loed in the center, and it serves as the ...
