Panasonic Will Power Future Teslas with Way Larger, Higher-Capacity Cylindrical Battery Cells

Panasonic has debuted its 4680 cylindrical battery that was previewed at Tesla’s Battery Day event last year.

The battery will purportedly store five times as much energy and cost half as much to build as the 2170 lithium-ion cells Tesla currently uses in the Model 3 and Y, which are also provided by Panasonic.

If this technology works out in mass production it will certainly be a game changer in the electric vehicle industry.

By products like solar panels and wind turbines are also great for the environment, (sarc) Reminds me of the battery charging station at my local gas station that has a diesel generator back up just in case. Liberal progressive stupiditiy

There are a number of comments in the car and driver article which explain that there is no big difference in power density for a car battery assembly; but a number of components in that assembly would probably be lower. (Think D Cells versus AA Cells in a similarly sized battery array box)

It took me six barrow loads of D-Cells to do the last battery change on my Tesla. I didnt mind the weight so much as the tedium of changing out all them cells.

For electric utility customers who have the option for off-peak free or negative priced energy, this development may help tip their decision into the EV option...at least for their around-the-town beater car.

Hopefully you sprang for the alkaline batteries over the carbon zinc batteries so you don’t have to do that so often. 😉😆

Canoo is claiming a range of 250 miles from a 80.0-kWh battery, with the base panel van version starting at $34,750.

Quadruple that. I'm not gonna park for eight hours waiting to bolt up.

Let me know when they invent a self-charging battery. Now that would be a game changer.

You may have already seen this, but just in case. Very funny:

The closest I saw to that concept came from a thermodynamically-challenged observer who suggested putting a windmill on top of the car to harness the energy of the passing wind and recharge the battery with that ‘free energy’ 😂

Yep, basically a bigger package of the same stuff and obviously cheaper to manufacture. But where it gets interesting is when a cell decides to have a bad day. Now you’ve got a ‘combustion event’ (battery talk) that is at least 5 times the size of the previous batteries. Will be fun to see what happens in those cases.

That’s a special kind of stupid right there.

I just got a mental image of a guy driving a Tesla with a grille like a 1938 Ford up to a Cumbys, unscrewing the grille shell and asking the clerk for an alkaline ZZZ battery two pack.

Watching “The Hunt For Red October” recently, I wondered why we just don't put caterpillar drives on all of the cars. Alec Baldwin would probably drive one.

The problem with teslas and electric cars unlike ICE vehicles that you can shut off, disconnect, kill the engine if the accelerater sticks,is....

.all those angry blue meanies ( electrons) ready to come full on lightning boltz fry your ass instantly right now , right in your face 24/7.

Ems, firemen and cops wont hesitate to sit there while they burn. They basically clear out the women and children for about a 1/4 mile while the angry pixies do their dance of smoke and destruction on you full size LiON RC car.

It sounds like a PR campaign for what will be a cheaper battery to make.

Who ever heard of cylindrical batteries, before? (That’s a joke). Almost all batteries used to be cylindrical. Open up your 9-volt or lantern battery and you find cylinders.

The problem is, they’re a waste of space. Cylinders don’t pack densely, which is probably important in a car.

.at least for their around-the-town beater car.
My beaters have bee from the 90s and earlier. They always cost under 3k and are usually large. I don’t have enough experience with electric cars to go that route when they are old and cheap enough.

Here’s how they will do it:

Yea, but you miss the point of buying an electric car - which is that gives you something to ‘talk about’ in your sparkling garage while holding your nose up at ‘socials’. Heck, for half of the people buying electric cars, you could remove the batteries (thereby making them safe) and the owners wouldn’t even notice.
