Energy density is just ONE of several important metrics by which a battery is chosen for a particular purpose. Charge/discharge rates, cycle life, temperature range and shock resistance are also necessary to consider, and all are in conflict with each other. Focusing on energy density to pick a battery is like choosing a new car based only on horsepower.

Gravimetric density is not the only metric by which cells are measured. You have to consider volumetric density as well. The 4680 cell has a volume of 0.133dm³ (litres). This gives it a volumetric density of 614Wh/l. The 2170 cell is way higher than this too

4680s are for the structural pack, so it's important to look at pack-level energy density and not just cell-level. Cheers:)

The Tesla Space: Range doesn't matter as much as people says it does. Oh really? I just drove from Houston to San Antonio, went to Fiesta Texas, Natural Bridge Caverns and Drove around Downtown and went BACK to HOUSTON. 480 miles ALL ON ONE TANK OF GAS costing $35. Thank you Honda Civic. Don't tell me range doesn't matter.

It’s not a good comparison to compare a brand new 4160 cell to a tried and true panasonic cell. They are definitely going to be limiting the new 4160 while it undergoes fleet testing. As the battery design is refined, it will gain in energy density. Meanwhile the 2170 isn’t going to gain much in energy density. The design is already optimal. And there is another point to this whole thing that you are completely missing. The 4160 cell is adding to the struxtural strength of the vehicle while the 2170s are decreasing the strength of the structure (they have to be carried). The way to think of this is that the 4160 is displacing some amount of steel that would otherwise need to be used in the frame. Think of this: start with a base car frame, now add 2170s. The additional load requires you to bring additional steel on the frame to hold the batteries. Now to move that additional steel, you need more batteries. So then you have to add more steel to support the additional batteries. It goes on and on like this until it reaches an equilibrium between number of batteries to carry and amount of extra steel to carry. Now think of the 4160. You start with a base car. Then you add batteries to the frame. That made the frame stronger and you don’t have to carry as much steel. And removing the steel means you don’t need as many batteries, etc., until equilibrium. There is a positive feedback mechanism to structural batteries. So you have to consider the weight of the steel you are replacing and how that weight reduction further reduces the number of batteries you need to get the same range. This additional efficiency IS NOT calculated in the energy density equation. So this is not a good way to benchmark a structural battery. The announcement on battery day that the battery is structural is honestly the biggest announcement they made… but for some reason it is so completely misunderstood by youtubers and media.

Tesla perfecting battery design is one of their best achievements, and my most favorite goal of theirs, I want them to get this right so badly. Keep up the great work Tesla. Thanks for this descriptive video.

You're reasoning is sound and your conclusions were well founded. Good job.

Are credit card unions safe as long as I have less then $250,000 there ? I'd also appreciate valid suggestions where to put the money substantial gains ,and as well hedge against soaring inflation

I wonder if they meant 10% over the 4680, or 10% over the 2170, the current production battery

Cybertruckin' down the road. Haulin' gear and a heavy load. Juiced up last night, gone at daylight. Family is ready to see new sights. Plenty of room with some to spare. So much power, none can compare. A few hundred miles go by real quick. Back into the campsite nice and slick.

Still don't know why they don't just use dilithium crystals.

Can’t wait to buy Tesla batteries like they are Duracell batteries

They speculated 18mo to fill ramp and have more battery lines coming online.

That was really good information hope we can get peace 🕊️

This video could have been roughly 4 or 5 charts and 3 minutes long. You make good videos. This one put me to sleep and wondering if I learned anything new.

This information is well behind the times as we have gen 3 cells being produced (so called cyber cells). And a 4th gen cell that incorporates more silicon in them for even more energy density. Energy density isn’t a big problem now and will Improve more over time.

My favorite part, was the 10% increase in density for the Cybercell !

400 miles is not enough for a pickup. And expecting Tesla to deliver on a promised feature "coming soon" is never a good bet: Roadster II FSD Service Repair Facilities Accurate range Self Parking with no sensors

You know you could have possibly have kept the original lithium recipe that made those metal dendrights if you where to some how implement a dendright breaker built into the chargeable battery kind of like a window wiper , but just made to scrape the dendrights off every few charge cycles.

lol he apologies for hyping and making assumptions about the old battery then immediately makes assumptions about the new battery... too funny

Thanks for this summary. So far Tesla/Elon have impressed us once - Giga Shanghai built and bringing online happened in record time in 2018. All other promises have been hot air and BS: e.g. FSD coming soon" said in 2016 and every following year!!

I especially liked the part where the other 3 Production Lines of Phase 1 4680 have just ramped up and 4 more lines in Phase 2 have started construction were completely ignored in the future production calculation...

Sem palavras esse documentário precisa nos mostrar em tempo real o que nossa preciosidade e capaz de fazer dentro e fora do inicio ao final ve lo em ação somos curiosos sim uma pessoa fazendo o texto seria muito melhor sim

I've seen an article about new Nasa solid state batteries with very promising specs. I wonder how real they are and when they have a production methode setup?

The first 100 people to download Endel by clicking the link or scanning the QR code will get a free week of audio experiences! bit.ly/TheSpaceRaceendel

I think a 160kWh battery is certain. So basically 2 model Y batteries

NASA has a new battery with 500w/kg.

Good luck in the gens future i wish them the best hopefully in 30 yrs or so this jetson world will come to fruition but as for now i like my combustible sedans and sports cars 💪👍

Typically it’s more about cost savings than a better battery. Faster battery production, more automation, and less rejected cells makes for better costs. A little lower performance is worth it. Even healthcare is more about managing money than actual management of health.

No but the dimension will tell you if it fits.

You cannot sell a product that under delivers on its specifications.

I don‘t quite understand the battery line optimization v. new lines rationale.

And then came the Solid State battery

😮

I fear that Elon's recent X-Post showing the bullet dents in the CT door was a window into his frustration with the truck, cleverly turned into a demo of it's durability.

Hummer EV 250 kwh around 48 empg

Tesla has spent the last three years learning how to build batteries at scale. They will now spend the next several years figuring out how to build more energy dense batteries at lower cost. This will be critical as they use the 4680 battery across their product line.

It's gonna be fun watching all the Reddit comments from these upcoming Cybertruck folks who have likely never even sat in a pickup. I especially look forward to all the "Elon said this would fit in my garage" comments. 🍿

one thing you forgot to add an your equation's (REGEN BRAKING)

Troy has no idea, stop using him as some sort of battery expert, he's not. The Limiting Factor is the GOAT for batteries.

even if its the same cost and lifespan and density they are getting massive subsidy making it for like 40 cent /kwh but it probably is better :P

Cyber truck is fundamentally different than the other Tesla. Even though it's shell may be streamlined it is still a utility vehicle. So comparing cybertruck to other Tesla models is useless. In short, cybertruck should be a hybrid of some sort. A hybrid would require less battery capacity and extend the range simultaneously

Just use 46x120 cells

I have a 2170 for Vape Mod 🤣🤣

It's funny how many times you call out promises.. I never heard Elon say I promise , stating engineering objectives isn't promises

The machine doesn’t have to be change they they are not upgrading mechanical change. That might be why they did the 10% mechanical change and create the line. Chemical change requires minimum line change I think.

There must be lots of ranches in the USA for all these trucks

"very unique" Makes my teeth itch. If something is unique is not like anything else. Unique has no degree, not "very unique" or "very unique". BY definition.

The future is more LFP batteries but more needed if in a truck as less dense

Still hoping he can build his battery banks in Texas like he was planning... maybe lower the price of electricity by a fair margin...

Ya know it would be kinda fun to play with carbon like carbonated wood ash and pressurise the gaafligifity out of it

most people that have trucks do truck stuff just ask Home Depot / Lowes or neighborhood of someone who owns a truck lol ..

Is there any lithium in these cells?

The more a vehicle weighs the more it has to stay on roads than can support its weight.!!🤨

Please don't say "very unique." Unique means one of a kind. Therefore, something is either unique or it isn't. There are no degrees of uniqueness.

When will battery mfg use AI to make Better Batteries 🔋?? Or is AI Over Hype 🤔??

Your data is inaccurate!

Just say the battery is about 50% larger and hold about 50% more energy. That alone would literally cover the entire video.

Good investigated work thanks. I’m rapidly loosing my positive opinion of Elon Musk’s abilities because of his over promising. He’s now joining the common ranks of OEMs.

I doubt it’s 80mm tall. The most common lithium battery is probably the 18650. 18mm wide and 650mm long. There’s another lithium ion cell called the 14500 which is 14mm wide and 500mm long. A standard AA battery has the same dimensions as a 14500 so you can get a better idea of the relative size in your head. Whatever the reason for the naming scheme of the 4680 battery I am going to assume it is 46mm wide and 800mm long. A 46 x 80mm battery would look like a chubby coin cell.

the Cyber Truck is just a fad it's Tesla that's the real deal

This is silly, all they need to do is have two battery packs onboard, with one of the self-charging battery banks at rest that needs to be charged while not under load, which would provide unlimited range with the current technology. The solid-state batteries will be much lighter and have faster recharge rates.

As a KZfaq Premium subscriber, it's frustrating to see ads in videos despite paying $15/month for ad-free experience. Unsubscribed.

So we take the sums done by some twitter rando as gospel? Really?

“Charging is subjective” That is the stupidest statement that could be made!

That's a lot of energy in a small space. Beware. I also saw a guy with the mac daddy battery pack charge a Hummer... it ticked off right around $100. Pass.

Just put induction coils in the road and let me charge as I drive. And hurry up!

Ah, but is not Tesla.... for losers? 🤔

Well calling this vehicle a truck in the first place is a misnomer. That ugly, overweight vehicle isn't a truck at all. It's a waste of time and materials.

Who cares about non-LFP and non-prismatic garbage?

Defund Elon!
