So, the Mach E uses pouch type battery cells. Recently Volkswagen announced they are moving away from pouch to prismatic cells, like the ones in your phone. I don't know much about such things but after 5 minutes of googling I can't see an advantage to this move other than perhaps cost? Just throwing this out there in case anyone that actually knows anything about this topic wants to comment
This article cites safety due to lower energy density: Volkswagen may switch from pouch to prismatic battery cells | Autoblog
Is that really true? I can find other articles saying pouch style is safer because it can expand, so is less likely to explode anyway. Pouch appears to be lighter, smaller and more versatile, so later VW EVs will have bigger and heavier batteries? That is the wrong type of evolution.....
In the meantime I think that leaves me happy with the pouch batteries in the Mach E
With regards to energy density they don't seem to factor in the intrinsic dangers of filling ICE vehicles with petrol....
