Yeah, that isn't showing the benefits of the 4680. It is showing future goals. The 4680 isn't going to provide an increase in energy density.

They were vague on purpose hoping people would draw this conclusion. The 4680 doesn't provide a 54% improvement. That is technology they are working on for the future.

If it was five times the energy density, then that would give you five times the range. That would be a battery with around 1,250 Wh/kg. If that was announced, Tesla stock would be would have skyrocketed. No, the energy increased is because of the size increase. The energy density decreases...

But then why do they say the 4680 has 5X the energy when it is 5.75 larger in volume. The energy density is slightly lower than the 2170 cells. That 54% increase is likely not from the 4680 cells, but rather their goal to reach eventually.

It is just a bigger Cell. It makes it cheaper to produce. At the pack level, there might be some increase in energy density, but it isn’t 56%.

I think they will do that anyway because the new batteries won't have the power density for the cars, but will for the CT and Semi. I think the roadster will need to stay with the higher power density & energy density cells.

To which density are you referring?

I would think its size would suggest they are going to make larger packs with lower power density, because a larger cell would be harder to cool. If the cell volumetric energy density isn't higher, the pack energy density is going to be lower because of the increase in space between the...

Our emissions aren't the biggest problem. It is the destruction of our carbon sinks that are the primary cause of CO2 level rise. 80%-90% of our forests are cut down for meat production, and our oceans are poisoned by the wastes and chemicals used produce the feed for those animals.

Do you know that animal agriculture is the single largest contributor to climate change, water pollution, soil erosion, ocean dead zones, and deforestation?

Just because you can buy a car doesn't mean you actually know how it works. The fact that you even made this comment makes you sound extremely ignorant.

Has anyone been following this battery technology? I find it fascinating that its capacity increases significantly from charging and discharging. It starts at 300Wh/kg and goes up to over 1,800Wh/kg. The data starts to disperse at that point, but it would be amazing to see a chart like this...

That is a great resource! Thank you!

But if the EPA says this model has 300 miles of range, what speed is that based on? 55? 65? 70?

I see many companies using different speeds for range estimates. Those of you who own Teslas, what is the speed that gives you the advertised range? Does the vehicle change the expected distance remaining based on your speed? For example, if you are doing 70MPH, and you slow to 55MPH, does...
