New page

{{right|Non-rechargeable Specific energy: 1300 Wh/kg Specific power: 200 W/kg}}
{{considerations}} __NOTOC__

==Considerations==
===Rechargeability===
{{sum|None|bad}}

Not suited for [[electric vehicles]]{{x|because, although it could have a very high range like 1000km or more, you wouldn't be able to charge it; it could only be swapped out; swapping out early (to running out of energy and getting stranded) would be extremely wasteful}}nor grid [[energy storage]], because the batteries are '''not rechargeable'''.

Maybe suited for [[electric planes]], because...
* batteries can be made in specific sizes suited for flight lengths
* the high energy density may well be worth the disposability
* battery voltage and output power remain stable throughout usage (important because full power is always needed for emergency landings).


===[[Energy storage/EROI|EROI]]===
{{sum|Very low|bad}}
{{dp|al_air_battery.energy_by_mass|1300 watt hours per kilogram|Typical "specific energy" of an aluminum-air battery}}
{{dp|aluminium_production.energy_by_mass|17000 kWh/tonne|Energy required to produce aluminium metal|"Aluminium production is energy intensive. About 17,000 kWh of electricity are required to produce 1 tonne of aluminium." [www.sciencedirect.com/topics/engineering/aluminum-production Aluminum Production - an overview - ScienceDirect Topics]}}
{{calc|al_air_battery.energy_by_mass / aluminium_production.energy_by_mass|%||Energy return on inputs - quick estimate}}
This alone shows how [[energy storage/EROI|inefficient]] it would be to manufacture a new battery every time we want to store some [[energy]].
{{minor|It would actually be ''even more'' inefficient in real life: The above calculation didn't factor in the energy to construct the battery, just the material (aluminum).}}
Such a low EROI might still be ok in the case of [[electric planes]], as planes are only a very small fraction of the world's transport-related energy use. {{pn|TODO: add pie chart}}

===Energy density===
{{sum|Very high|good}}

Typical: 1300 watt hours per kilogram 
Attempted: 2000 watt hours per kilogram

These are far higher than [[lithium-ion batteries]] which are only about 200 watt hours per kilogram.

===Materials===
{{sum|Abundant|good}}
Unlike some [[lithium-ion|other]] battery types, aluminium-air batteries use mostly just aluminium, which is one of the most abundant metals on Earth.
