Panasonic to Deliver 100 Millionth Lithium-Ion Cell for Tesla Model S by End of June

How many lithium-ion cells will be in Tesla Model S sedans by the end of June?

Well, if it not for an announcement by Panasonic, we wouldn’t be able to answer that question.  But, surprise, now we can.

Panasonic says that it’ll ship Tesla its 100 millionth lithium-ion cell before the end of the month and that by month’s end, that figure will easily surpass 100 million.

Since Panasonic is only referring to Model S specific cells here, we could try to break out how many Model S sedans Tesla will have built by the end of June, but therein lies the problem.

There are two versions of the Model S currently available, both of which use a different amount of cells.  So, it becomes a guessing game of sorts to figure out a precise production number.

We do know that the 85-kWh version of the Model S “consists of more than 7,000 battery cells,” according to JB Straubel, Tesla’s chief technology officer.  So, if we falsely assumed that all Model S produced by the end of June were of this version, then we could say that Model S production would be at approximately 14,200 units.

Officially, we pegged Model S sales at 11,150 units at the end of May.

We’re not sure what else can be drawn out of this 100 million cell announcement.

Perhaps some of you will find a way to translate it into total a production figure and possibly even a 60-kWh versus 85-kWh breakdown.  It’s worth a go, right?

    Inputs into Tesla’s inventories do not equal sales by Tesla. There’s a multi-month pipeline there. Also, you have to account for producing units for spare parts and test vehicles.

  2. Bernhard says:

    Both models (60 and 85 kWh) feature the exact same number of cells, just a different capacity per cell (and therefor a lower price). Also the more or less same weight of both models points into that direction.
    Guess: 85 kWh uses a 3.1 Ah version and 60 kWh the 2.1 Ah version.

    1. GeorgeS says:

      That’s interesting. I know the 40 ah S had the lower ah cells but thought the 60 and 90 used the same…..but I guess if they have the same wt that could point to different cells (or somerthing else perhaps)

    2. GSP says:

      The 60 kWh model has a lower curb weight. It most likely has less cells.


    3. Lol says:

      Yeah, good guess. I’m sure they needlessly complicated things by designing 2 completely different cells when they can just use fewer cells, and accomplish the exact same thing with less weight.

    100 million cells is enough to cover an 8 acre area full of cells.
