4680 cell improvements by 10-20%

[Darth abbott]

Rumor is that Tesla is finalizing a new cell format which has 10-20% more energy density. If true the cybertrucks battery would have a pretty good gain in range. With the same amount of cells. Now Tesla could just use less cells than and keep the range the same but let's say they give us the gains. My question is would you wait say 3-6 more months for a 10-20% increase in energy out of your battery?

Yes

Normally I'd expect Tesla to use that energy density increase as an excuse to put less batteries in but the range is so anemic for a truck it seems like they would have to increase range.

Keep in mind that 10-20% less batteries is a weight reduction, which would increase range as well. Many different ways to look at a change like that.

I hope it's more range.

As much as I want them to implement this I don’t see them doing it solely to save on cost.

Yeah from Tesla standpoint, if they reduce the weight and that increases range, and they can reduce the amount of cells which also reduces their cost on the truck, they could go that route. I mean I hope they don't do that I hope they keep the amount of cells that are currently there and just give us the added range, which I'm kind of thinking they would do because they're not increasing the amount of cells they're just increasing the energy efficiency of them. And it would help to increase positive information about the cyber truck and range.

Really 20% ? That will require whole battery chemistry to be changed. Sounds like more rumor to me. Tesla just reduced range estimates for model y,s and x

The rumor comes from the employees building the cells. Supposably. It is changing the chemistry of the cells. If you Google it you can find YouTube videos and articles on it.

The 4680 is already a new chemistry that has gone through several iterations already. If they have made an improvement to a specific part of the anode, or cathode then it will not need a complete overhaul of the battery. When Tesla purchased Maxwell for their dry electrode tech they had a planned roadmap for achieving higher density each year but certain hurdles have obviously been difficult to overcome. Just like the other vehicle components, I would assume a change in the chemistry will not set them back more than a couple months at the most to implement. It’s like swapping out one specific part on the assembly line. It would be amazing news if they achieved another 10 or 20 percent energy density. Makes the range extender all the more desirable to act as a home power wall for less money.

Rumor from where?

I saw a thread about it yesterday
Title: New 4680 battery chemical makeup coming [link]
and then an article about it last night.

Wait a year if you can.

Which allows you to remove even more batteries, to keep the range the same. $$$

Reposting this from another thread since I think it's very relevant to this discussion:

My Yukon holds 26 gallons of gasoline, which at 33.7 kWh/gallon is energy storage of 876 kWh. The engine's thermal efficiency is about 30%, so in terms of useable power that isn't wasted to heat that's an effective energy storage of 263 kWh. The Yukon's drag coefficient is about 0.38 compared to the Cybertruck's 0.34, both vehicles with a comparable height and width, so you can further factor down the effective useable propulsion energy to (0.34/0.38)*(263) = 235 kWh in order to make an apples-to-apples comparison with the Cybertruck.

This tells me that if they put a Hummer EV battery pack (200 kWh) into the Cybertruck's streamlined body you would get highway range comparable to my Yukon's. Until we see energy density in batteries double compared to today I think that you're always going to take a big hit switching from ICE to EV for highway driving and towing.
