Is Lucid Panasonic battery chemistry that much ahead?

"Solid-state batteries generally offer a volumetric energy density ranging between 800 Wh/L to 1,200 Wh/L at the cell level."

"Lucid’s high-performance battery packs achieve an industry-leading volumetric energy density exceeding 800 watt-hours per liter (Wh/L)."

"Contemporary Amperex Technology Co., Limited (CATL) has set the production threshold for large-scale commercialisation of solid-state batteries at 1 million vehicles, an industrial volume projected to remain unattainable before 2030."

"The Tesla 4680 battery cell achieves a gravimetric energy density of 241 Wh/kg and a volumetric energy density of 643.3 Wh/L. This high energy density is primarily due to its NCM811 cathode chemistry and optimized tabless cylindrical design."

So:

Lucid cell chemistry holds around 840 wh/L.
Around 30x 2170 can fit into 1 liter of space, each cell weight around 68g, so 1 liter can fit around 2kg of battery.
This equates to 420 wh/kg.
Donut Lab solid state faking 400wh/kg.
Tesla 4680 is 241 wh/kg.

Is Lucid cell used in Gravity that much ahead?

I really don't know the answer to your question. But it does seem like battery claims are shrouded in a swirl of difficult to compare stats. I doubt that Lucid's battery chemistry is fundamentally ahead of what the rest of the industry is doing for liquid electrolyte batteries. Since battery chemistry technology is generally owned by suppliers, and not the vehicle manufacturers, it seems unlikely that any single vehicle manufacturer is going to be substantially ahead of the rest of the pack, except for perhaps short periods of time related to product development cycles. To do otherwise would require being a big enough manufacturer to strike an exclusive deal with the owner of a battery chemistry improvement. Much as I love their vehicles, Lucid is not big enough to strike that kind of deal.

From interview with Emad Dlalah, it appears that the chemistry is Lucid specific that was co-developed between Panasonic and Lucid.
I would imagine its for Lucid use only.

Similar Panasonic cells have volumes of .023 to .025L, so the cell volumetric conversion is closer to 40-43/L. This increases the weight and makes the wh/kg in the high 200s, which is still strong, but around 25% lower than a 400 wh/kg threshold.

Where did you source that data? The Lucid LG/Panasonic cells are nothing special. Their volumetric density is probably 20% lower than you state.

Is that what you mention? Here is the latest interview I've found:
