Tesla To Get Faster-Charging Energy-Dense Battery Cells From Panasonic

[TMC Staff]

Panasonic has already started converting production lines at Tesla’s Gigafactory 1 to produce the new, improved cells. According to information from a recent lecture for the Stanford StorageX International Symposium, Panasonic‘s new battery cells not only offer greater energy density, but also have improved fast-charging performance. This means Tesla’s future vehicles will charge faster, but we have no...

Will the older cars get the new cell packs when those cars need to have their packs replaced?

Do these cells explain the recent range increases?

In my opinion:

Once Tesla starts production of any "Model" why would they want to change battery format?

Consider Model S 18650 - no competitor yet. quickest; longest range; most efficient (cheapest to charge). Also, considering continuous improvements we have many other improved parts.

I guess most do not realise all the costs involved in changing cell format [read - size] module; pack; electronics?; how do pack changes [don't forget size changes] impact the skateboard; body; doors; trunk; hood. Let us not forget supply chain disruption/changes; parts catalog, warehousing. Is there ANY ROI doing such a change? Will people PAY more? how many more? (Same for Model X.)

Would not surprise me if different factories [especially on different continents] use different cell formats (or chemistries) depending on supply chain [read - where batteries are sourced].

Tesla will consider all these variables (and many more such as import/export/transport ...)

And of course volumes matter as economics/costs change depending on volumes. So I see no changes for S/X as volumes are low and only one factory so far.

It will be interesting to see how this all plays out for Model 3/Y as we already have different factories on different continents. Vehicles are a complex business.

side note: I can't believe how many different Mustang Mach E offering Ford has (all from one Mexican Factory)

There is no indication that they are changing cell format. It seems to be a tweaked chemistry or materials in the same cell format.

18650; 2170
Chemistry has always been changing - and may now have 3 different chemistries being made for different applications

4680 seems they plan using 3 different chemistries (for now)

Tesla corporate secrets, I think, so little known about different amounts made

Who really cares? competitors, battery companies but to an end user it is like knowing paint formula.

Perhaps a change in size shouldn't be included in format. My bad. Poor use of language. sorry

Tesla has always used cylinder format cells (of different sizes).

Is Tesla still using 1650 batteries in any of their new cars? If so, i imagine that model S would be one of them. Hasn't the model 3 always been using the 2170s? Just curious, i'm new here.

I meant the 18650 battery. Would have fixed but couldn't find an edit button.

Model S/X 16850 cells
Model 3/Y 2170 cells

I don't know which chemistries when

Thank you.

The pack revision letters probably indicate changes in chemistry.
