On: A novel solid, rechargeable air battery

While probably not ideal for a phone or car, it could still have its uses. So long as it stabilizes at that 70%+ region, that is not potentially a deal-braker for grid installations. Which is an optimization of installation cost, maintenance, longevity, operating temperature/pressure requirements, charge/discharge rates, etc.

They didn't say it stabilizes, though. You'd think they'd mention that if it did.

If it stabilized then it would just be 30% heavier. I doubt it stabilizes.
