The
alkaline battery is
different from 'normal' batteries in that
they have an alkaline
electrolyte. This electrolyte usually consists of
potassium hydroxide. The positive
electrode is made from
manganese
oxide while the negative consists of
zinc oxide.
The alkaline battery has a larger effective
temperature range than
normal batteries, and can be used between -30°C and 70°C. It
also has a higher energy
capacity. This means that the alkaline battery
can supply higher
currents, over longer time. Because of this the alkaline
battery has become very popular, and is
rapidly becoming the
leading battery type on the market.
