I agree with you one of the key metric is getting enough range. So if you put $ on top, $/range is an important metric.
Range = energy/weight (all else being equal)
I said energy/weight matters because ultimately it's about $/(energy/weight). If not, salt batteries would be in the conversation due to their excellent $/energy ratios. But they are not because their energy/weight ratios are so awful their $/energy advantages are completely overwhelmed.
The term you’re looking for is energy density.

Imo it seems very likely that Tesla have in fact made a proof on concept production line with “next gen battery” depending on definitions. If you read between the lines of lots of patents, statements, acquisitions, imo it seems very likely that Tesla has done a few selected investments, had a few prominent researchers work for them and have made a few specific improvements that together will bring a battery that performs well, is cheap and scales well. My own guess would be:
>320Wh/kg cell level, >1M miles cycle life, <$80/kWh cell and <50% factory footprint. Imo this qualifies as “next level battery”. Would not be surprised at >350Wh/kg and <$80 pack level.
We will see at battery day who was least wrong.
1. Which company have you invested in?
2. I rounded down to 0%
3. I’d love to hear which acquisitions/investments/prominent researchers you think help tesla in this area. You clearly are hinting at something. (Fyi unlike others on the board I genuinely would like to hear something I don’t know. As of now I disagree with your opinion.)
4. Lithium batteries don’t work like that. You don’t just bring in a few smart guys and poof the price drops 50% with increased production like that.
5. When is your prediction for actual manufacturing of that >350, <80 battery? Without that it’s worthless. There are several non-economically viable lab batteries that crush that energy density.
Bloomberg New Energy Finance has bumped up their projections to get around $100/kwh in 2023. They don’t say explicitly but their projections seem to imply around $75 by 2025.
I personally believe both of those will be earlier, but not from in-house tesla.
Getting meaningfully above 350kwh I believe involves a chemical move away from lithium-nickle,magnesium, cobalt or whatever similar mixtures they’re using now. Many chemical breakthroughs require a totally different assembly line construction. You’re telling me Tesla will have that in-house battery being manufactured at Fremont in 2020?! Wild stuff.
6. Patents without peer reviewed research and a realistic manufacturing plan aren’t worth the e-paper they’re written on.
7. Not sure what you mean by factory footprint.
They obviously are going to say SOMETHING good on battery day that’s not just blatant deception. Odds are it will introduce at a minimum a tesla battery manufacturing line and declare ramp up goals. But anything meaningful in cell breakthroughs - don’t hold your breath imo. Stick with the 1 mil mile battery message (as if that matters)
