The term zinc–air fuel cell usually refers to a zinc–air battery in which zinc metal is added and zinc oxide is removed continuously. Zinc electrolyte paste or pellets are pushed into a chamber, and waste zinc oxide is pumped into a waste tank or bladder inside the fuel tank. Fresh zinc paste or pellets are taken from the fuel tank.
Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion. As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here. [64]
As of 2014, Fluidic Energy is the only company selling commercial rechargeable zinc–air battery systems. Fluidic Energy has been selling commercial backup solutions for telecom sites and in emerging regions [ 10 ] since 2011 and has moved into microgrid and other long duration applications. [ 4 ]

Zinc-air hearing aid batteries. Miniature zinc-air batteries are button cells that use oxygen in air as a reactant and have very high capacity for their size. Each cell needs around 1 cm 3 of air per minute at a 10 mA discharge rate. These cells are commonly used in hearing aids.
Aluminium–air batteries have the highest energy density of any other battery, with a theoretical maximum energy density of 6–8 kWh/kg, however, as of 2003, a maximum of only 1.3 kWh/kg has been achieved. Aluminium battery cells are not rechargeable, so new aluminium anodes must be installed to continue getting power from the battery, which ...

The facility produced hearing aid batteries, aluminum-air batteries, C and D zinc-carbon batteries, and six-inch dry cell batteries at various times. It was closed in March 1998 following the decline in demand for zinc-carbon batteries. [38] Eveready opened a plant in Bennington, Vermont in 1942 and a facility in St. Albans in 1947.
