German scientists have applied a new combination of cathodes and electrolytes to improve the stability of lithium-metal batteries. They fabricated a device with an energy density of 560 watt-hours per kilogram and a Coulombic efficiency of 99.94%.

Researchers from Germany's Karlsruhe Institute of Technology (KIT) and the Helmholtz-Institut Ulm (HIU) have built a lithium-metal battery with a new combination of cathodes and electrolytes, which they claim can help the device reach an energy density of 560 watt-hours per kilogram.

The battery is based on a low-cobalt, nickel-rich layered cathode known as NCM88, which the scientists said offers a high energy density and improved stability for the battery compared to commercially available organic electrolytes known as LP30. “In the LP30 electrolyte, particle cracks occur on the cathode,” HIU professor, Stefano Passerini explained. “The electrolyte reacts within these cracks and destroys the structure and thick, moss-like lithium-containing layer forms on the cathode.”

With the efficiency at 45%, that’s a pretty big difference. Many ICE vehicles will get about 20% to 40% loss of efficiency.

if i am briefly skimming the article 200-300 ranges become 400-600

once they get to 3000-5000 mi/chrg it will be usable:

The question is..Does it come in AA?

Putting some big muscles on the bunny.

Is the explosive power proportional to the increased capacity?

[Beagle8U]

Or a elec leaf blower that would do a whole neighborhood?

Here is a picture of the thing:

Rather than all the wasted money on elec cars that don’t work it would be better to allow UTVs for city driving.

For about $8k you can get a 4x4 UTV that seats 2, gets about 50 mpg, goes about 30 mph, will haul 1/4 ton, and will go in 8” of snow and ice.

For the price of one small car you could buy 3 UTVs, enough for the whole family to drive in any weather rain or shine, summer or winter.

“Is the explosive power proportional to the increased capacity?”

My first thought, also. Still helping a buddy repair his garage that caught fire when a LI battery exploded.

50 mpg? Which UTV are you referring to?

[Beagle8U]

I haven’t checked mine because it has no odometor, but the Kawasaki Mule must get close to 50 MPG?

They seem to go forever on a tank a gas.

[Beagle8U]

I did some more checking and I guess it would be closer to 25 mpg.

The Kawasaki Mule has a 4 gal tank and is only 13 HP. They seem to go forever on a tank of gas.

This means the fires will burn hotter and brighter.
