aluminum-air

Eventually, both Aluminum-Air and Lithium-Ion batteries will wear out and need to be replaced, but the Aluminum-Air batteries need to be replaced more often since they wear out faster.

The Aluminum-air batteries do wear out eventually as they turn the aluminum into aluminum hydroxide, but they can be recycled.

So the energy per mass for aluminum-air batteries could be up to 80% to 85% of that of lithium-air batteries.

The Aluminum-Air batteries are rechargeable, but they wear out faster than lithium-ion batteries.

I remember a few years ago a company that was developing an aluminum-air battery was demonstrating an EV using it.

So the preeminent difficulty with aluminum-air is the cost of aluminum.

I’d go with shipping energy as aluminum or something like that and use aluminum-air batteries.

As I alluded to in my grandparent comment, aluminum-air batteries were mass-produced in the 01960s.

Unless we get something like aluminum-air batteries that can exploit oxygen in the air somehow.

With swappable aluminum-air batteries you'd have both distributing the new batteries to the swap stations and distributing spent batteries to the smelting and battery making facilities.

Cables provide efficient JIT power delivery, but they're vulnerable to precision-guided missiles, which Ukrainians are 3-D printing in their basements by the million, so the aluminum-air battery may return to commercial use.

Because the car would still rely on its regular rechargable lithium-ion battery most of the time and would switch to the aluminum-air battery as a backup only if the lithium-ion battery ran out, and because most car trips are 50 kilometres or less, Alcoa estimates the aluminum-air batteries would only need to be changed about once a year.

From the ComputerWorld article: > "The recharge of the aluminum-air [battery] is user-friendly and consists of refilling water and replacing aluminum when depleted," a spokesperson for Alcoa said in an email response to Computerworld.

That is the intent => "the car would still rely on its regular rechargable lithium-ion battery most of the time and would switch to the aluminum-air battery as a backup only if the lithium-ion battery ran out"

This is a chemical battery with very limited lifespan.

Aluminum-air batteries react the aluminum in the battery with oxygen from the atmosphere producing aluminum oxide.
