This is regarding Aluminum air batteries

Since they are rechargeable, inorder to "recharge" the batteries we need reswap aluminium cathode with aluminum hydroxide which is formed.

And that aluminum hydroxide needs to be processed to extraxt aluminium. How efficient is extraction of Aluminum from Aluminum hydroxide?

An Inturn what is the efficiency of Aluminum air batteries, assuming swapping takes no energy?
