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?

30+ here. Drink more water, wear sunscreen, take photos of your friends, and don’t marry someone just because the Wi-Fi is shared

Me too, came from reddit.

Same here. I’m still on Reddit, but the moderation can feel unpredictable, and it’s discouraging when normal comments get flagged. Finding Lemmy has been refreshing, and I’d like to see the community grow into something sustainable and balanced.
