Aluminium–air batteries (Al–air batteries) produce electricity from the reaction of oxygen in the air with aluminium. They have one of the highest energy densities of all batteries, but they are not widely used because of problems with high anode cost and byproduct removal when using traditional electrolytes.
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 ...
Aluminium-ion battery is a class of rechargeable battery in which aluminium ions provide energy. Aluminium–chlorine battery was patented by United States Air Force in the 1970s and designed mostly for military applications. They use aluminium anodes and chlorine on graphite substrate cathodes.
Essentially, a battery makes electricity from a chemical reaction; when you charge it, you use electricity to reverse that reaction. Each comprises three essential parts.
Another approach to an aluminium battery is to use redox reactions to charge and discharge. The charging process converts aluminium oxide or aluminium hydroxide, into ionic aluminium, using electrolysis, typically at an aluminium smelter. This requires temperatures of 800 °C (1,470 °F). One report estimated possible efficiency at around 65%.
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]

A rechargeable battery, storage battery, or secondary cell (formally a type of energy accumulator), is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use.
