Tesla 2170. But pricey

These cells are probably 10 amps continuous considering used one in the Model S before recent updates.


people buy and sell these packs all the time. Wrecked cars…

2170’s should offer an increase in cell capacity. That is: 21mm wide x 70mm tall. That’s 3mm wider and 5mm taller than the previous 18650 cells used by Tesla in the past, but now, that size increment translates in 15% more energy density than in previous cells. This will translate in an increment of energy storage and at the same time a significant battery weight reduction with an improvement up to 40% efficiency in some cases, depending on the type of electric motor (kWh) Tesla will use.

According to Tesla:

“Cells used in Model 3 are the highest energy density cells used in any electric vehicle. We have achieved this by significantly reducing cobalt content per battery pack while increasing nickel content and still maintaining superior thermal stability. The cobalt content of our Nickel-Cobalt-Aluminum cathode chemistry is already lower than next-generation cathodes that will be made by other cell producers with a Nickel-Manganese-Cobalt ratio of 8:1:1.”




It’s all about the cobalt. They need it all for themselves.


There’s probably plenty of cobalt around the world. Just not many established mines yet. This is about to change though.

There is future in Cobalt mining then! I remember during the old days of printed Photography and dark rooms, Kodak used like 85% of all the Silver produced in the world for their photo paper emulsion! It was insane. They were the largest consumer of Silver in the planet.

Best if we together buy a model 3 salvage pack and split it

Now that a grrrreeat idea! Will be awesome if we could conform a group buy for this purpose. :yum::+1:


Looking forward when they manage to cut cobalt completely, luckily in the next iteration of the cells

Model s yea. Not model 3 packs

Cobalt isn’t the future. Cobalt production is a byproduct of copper and nickel ores. And it’s mined in Africa using partly child labor with labor practices considered questionable.


Hip hip hooray!

tell vegans that. They go into denial
