Did not mention cycles. It's a 920kwh "useful" battery. Which means it will have a higher capacity but be limited to preserve life.
Side tangent, keeping your battery between 40%-80% charge will significantly increase its lifespan. Something like 6x the lifespan vs always charging to 100%. Low voltage and high voltage contribute to damaging cells at a faster pace, which is why leaving your device charging overnight is so bad. I have only charged my non work phone and iPad to 100% a half dozen times (by accident) and rarely let them go below 40%.
Of note on batteries, the inventor of the current day lipo battery has discovered a new way to produce them. No degradation and tens of thousands of cycles, no fire risk, and lighter. He has street cred. Hopefully it pans out, it could revolutionize transportation.

All we can do with batteries is improve the efficiency of known chemistry towards the theoretical max. Also improve cycle life and charge cycle degradation characteristics.
Right now mature (commercially viable) battery technology can get to around 200 W hours/KG. Theoretical chemical limit is about 1,000 Wh/KG.
Jet A is 12,000 Wh/KG...
There's no uncharted territory in molecular chemistry which is going to provide an order of magnitude+ improvement in specific energy. The answer is going too be biofuel.

Or build a nuke power plant and count the natural gas you are NOT burning as recapture.

Cheaper - by far - to just use fossil fuel and offset the carbon release with carbon capture technology. Doubt that will change in the next several decades, at least not without a hellacious capital investment that would take even more decades to recover.
