Chinese battery maker CATL says it has cutting-edge technology able to surpass limits that have held back battery development worldwide, ushering in a new era of electrification for passenger aircraft. These are bold claims that, if they come to fruition, will shake up battery technology as we know it.
Battery density signifies a key metric in creating a lithium-ion battery that’s both powerful and light enough for versatile applications, such as an aircraft. Current understanding of technology has the densest lithium-ion batteries generally hovering below 300 Watt hours per kilogram (Wh/kg), but CATL says their new battery boasts a 500 Wh/kg density. This is especially promising for use in aviation due to weight considerations.
“CATL’s condensed battery leverages highly conductive biomimetic condensed state electrolytes to construct a micron-level self-adaptive net structure that can adjust the interactive forces among the chains,” the company says, “thus improving the conductive performance of the cells and, in turn, the efficiency of lithium ion transporting while boosting stability of the microstructure.”

To have more denser batteries than what we have, we would have to move beyond lithium because what we have with lithium is all we can have with lithium, imo.
Is the battery more dense than Brandon?
Maybe they mean like the Wright Bros. first flight across some beach sand.
Gotta start somewhere.
Several research labs in the U.S. are experimenting with doubling the capacity of lithium batteries.
Those lithium batteries have a reputation to go up in flames occasionally. So better design the plane with asbestos lining.
Even doubling wouldn’t be enough for a plane.
Doubling the capacity of lithium would give it about 1/8 the energy of a gallon of gas. Hardly anything.
There seem to be some laws of physics that militate against the miracle battery the Great Reset wants to will into being.
“Doubling the capacity of lithium “
Which you said couldn’t be done.
“Even doubling wouldn’t be enough for a plane.”
There are already electric planes in the air.
Doubling from nearly nothing to next to nearly nothing is not really an advancement. Get to me when they manage to pack in 33 MJ/L, like gasoline.
If they doubled the energy of lithium, they would move from
2 MJ/L to 4 MJ/L.

It is a dead-end path at the moment.
**Those lithium batteries have a reputation to go up in flames occasionally. So better design the plane with asbestos lining.**
Do that, and make an air inlet that can be opened varying degrees at the front of the plane leading to the battery box, with a fan propelled by a pop up bicycle pedal drive. And at the rear of the box install an exhaust pipe out the the rear of the plane. Voila, a secondary thrust system.
Never let a crisis go to waste. (As demcomms like to say).
” Get to me when they manage to pack in 33 MJ/L, like gasoline.”
But most of that energy goes up in smoke and hear. Then you have to factor in the weights of the motors and accessories.
You do the same with electricity. What goes in smoke in heat just gets displaced to the power plant.
Battery vehicles outweigh gasoline vehicles.
Every bit of a gas car can be recycled. We can’t recycle everything in a EV.
Ultimately everything about gasoline is reused by nature.
Hydrogen. Oxygen. Carbon. CO2. Plant Food. Water. What little real pollution that does get created decomposes into elements reasonably quickly.
500 watt hour per kilogram is impressive for a battery. Gasoline has 12,700 per kilogram and Jet A has slightly more. Good luck on flying from New York to London using batteries. The North Atlantic is cold and it will kill you quickly.
The only thing you are convincing me is that you like shiny things. :)

I just looked up the performance. These planes can run for about thirty minutes before they run out of juice.
So far, have only found the Alice that made one 10 minute flight.
Any that you know of that are FAA certified other than experimental?
