An example of a secondary cell is shown in the drawings below. The positive electrode is
made up of the positive plate group and the negative electrode of the negative plate group.
The positive plate group makes up the positive electrode. The negative plate group makes up
the negative electrodes. Placing the assembled cell in a container of electrolyte will cause a
chemical action that will generate electricity. A secondary cell differs from a primary cell in
that a secondary cell can be recharged and a primary cell can only be restored.
