20.7: Batteries and Fuel Cells
There are two basic kinds of batteries: disposable, or primary, batteries, in which the electrode reactions are effectively irreversible and which cannot be recharged; and
Primary Battery
Primary batteries are single-use galvanic cells that store electricity for convenient usage, usually showing a good shelf life. Examples are zinc–carbon (Leclanché) cells, alkaline
Battery
Each cell contains two types of electrodes, an anode (positive electrode) and a cathode (negative electrode), that together provide and absorb electrons with sufficient voltage (electromotive
