As discussed in the thread below, it now appears that if the model 3's new batteries are improved over previous generations, it is not in
having achieved a very significant improvement in energy density.
Earlier statement from TSLA:
having achieved a very significant improvement in energy density.
https://teslamotorsclub.com/tmc/threads/model-3-battery-details.96792/Ok I think I have to be the first to say this, so please brace yourself:
If the base Model 3 really has 50 kWh, as stated in the article, the cells are worse than the 18650s.
... the cells probably would have a worse gravimetric energy density, too.
Now add in slower charging and less performance and either the new cell format is just worse than the 18650s, or the pack has more than 50kWh total capacity.
Earlier statement from TSLA:
https://electrek.co/2016/11/14/tesla-model-3-battery-energy-density-model-s/Tesla Model 3’s battery will be 30% more energy dense than the Model S’ original pack
Tesla CTO JB Straubel:
...when we went from the Roadster to the Model S, they have improved by about 40% and when we were designing the Model 3, they were about another 30% better...

...The standard 50 kWh Model 3 battery pack is made of 2,976 of those cells in groups of 31 cells per “brick”. The bricks go into 4 separate modules (2 modules of 23 bricks and 2 modules of 25 bricks).
That pack is going into production later this year. Currently, Tesla is producing a 74 kWh ‘long range’ battery pack, which consists of 4416 cells in groups of 46 cells per brick and the same brick distribution in the 4 modules...
