Nickel–zinc battery

A nickel–zinc battery, abbreviated NiZn, is a type of rechargeable battery with a voltage of 1.6 V. Large nickel–zinc battery systems have been known for over 100 years. Since 2000, development of a stabilized zinc electrode system has made this technology competitive with other commercially available rechargeable battery systems. Cells in "AA" and "AAA" sizes are available.
