Famous as the raw material for dry cell bat-
teries, manganese is a metal found both on
dry land and on the sea floor. But while man-
ganese batteries have been in use since the
late 19th century, they are gradually being
replaced by the alkali family of batteries
(though actually there isn’t much difference
between the materials used in these two
battery types). Manganese is also necessary
for our metabolism.
