This is over three times the density I have seen posted for Pipitrel Elektro. That would be a game changer for endurance. At that point, the questions become cost, cycle count, degradation rate over cycles.I don't expect these to be manufactured next week, but there are very deep pockets behind the research. It's an existence proof that nothing's set in stone.
Development of a lithium-air battery with an energy density over 500 wh/kg: One of the world’s highest energy densities achievedResearchers have developed a lithium-air battery with an energy density over 500Wh/kg -- significantly higher than currently lithium ion batteries. The research team then confirmed that this battery can be charged and discharged at room temperature. In addition, the team found that the battery...www.sciencedaily.com
Time to climb to 3000 meters was done recently by a wankel powered Harmon Rocket. See Paul Lamar's blog. Come on Lithium/Air!!!This is over three times the density I have seen posted for Pipitrel Elektro. That would be a game changer for endurance. At that point, the questions become cost, cycle count, degradation rate over cycles.
Now comes the reality check: how far away this is from actual purchasable production. What the article did not say, and I did not see is if they have produced viable coin cell test units which can be sent out for others for verification. From what I understand, this is the first major step to production...
That's pretty much the description of the electric Beaver and the electric Caravan. Mostly batteries for really short flights.Does current battery tech mean it would be the size of a ten seater but only seat two, or is there sort of a ‘tyranny of the rocket’ thing going on where the more batteries you carry the more batteries you have to carry?
The spec you provide is what most pilots claim; but never flyI’ve been wondering, what would a ‘practical’ electric cross country two-seater look like? To be practical I’ll arbitrarily say it has to be able to go 1000 miles between sunrise and sunset and has to be able to fly when I want, not having to wait for ideal conditions (thunderstorms and icing notwithstanding).

I think to use these Lithium Air batteries safely you need to put them in kind of an air "Barge" and tow it around with an aircraft "Tug". The barge could be partially buoyant with Hydrogen gas no more potentially hazardous than the Lithium Air and besides the "Tug" can just release the "Barge" and fly away.BOOM! This just blew things the other way...
Uh, yeah, NO! Sorry. Lab experiment.BOOM! This just blew things the other way...
Exactly. By now, anyone over 40 should be skeptical of ANY big claims in aviation. If they're not, they face a lifetime of disillusionment.Uh, yeah, NO! Sorry. Lab experiment.
If you haven't ever looked up Lithium and air's constituents on the periodic table there might be a problem. When these things come out of the lab and someone tries to implement them IRL there is always some show stopper.
We only have one periodic table. People keep trying to move the blocks around to their advantage. Never pans out.
I want new technology. I don't want hollow promises of new technology.So, you both want old technology, not new technology...
Yup, just like the carburetor in the 1970’s that, when installed on any 8 cylinder, got 120 miles per gallon. Never available because the gasoline companies bought it and hid it. Yup, just like that.No idea about these Lithium/Air batteries, but the potential exists, as long as big money doesn't buy the rights and bury them.
