Futurology

Agreed — that’s the core issue. Aluminum-air doesn’t fit the mental model people have of a “battery” since it isn’t rechargeable in the conventional sense. Once you require anode replacement or external recycling, it stops competing with AA or Li-ion on convenience.

From what I’ve read, the hybrid demos weren’t true recharging but more of a fuel-cycle approach using aluminum as a consumable. That makes it fundamentally different.

That said, I’m not sure it needs to replace AA or Li-ion to be useful. Do you think there’s still room for technologies like this in niche or emergency scenarios where shelf life and energy density matter more than rechargeability?
