Road traffic signalling zinc air-alkaline batteries are EXTREME SAFETY. Long operating time. High and constant voltage.Flashing lights, Cascades.
ZINC AIR BATTERIES use atmospheric oxygen to produce electrochemical energy. Since one active material lies outside of the cell, the majority of the cell‘s volume contains the other actice component (zinc), so zinc air batteries have very high energy density. Using a reactant from the air saves on space, reducing the size and weight of the battery.
