First of all, I'm not complaining. Just mostly curious about the rate at which Lithium Ion density improvements are being made over time... I also get that having something in the lab and mass producing it are completely different things. However, Tesla was essentially mass producing 85kwh packs in mid-2012. Now we are in mid-2015, three years later. After reading various articles and threads like this one (How fast is lithium-ion energy density improving | Forums | Tesla Motors) stating that JB has claimed 8% year over year improvements, I was under the impression that if a new pack were to come along this year, we'd see something more along the lines of a 105kwh pack by now (3 years after 85kwh delivery @ 8% improvement per year = 107kwh). Even going by Elon's recent comments of 5% improvement year over year going forward, it seems we should still have seen a 95kwh pack (85kwh with 3 years @ 5% growth = 98kwh). Was anyone else a bit surprised that the pack was not denser, given the previous and currently stated trajectories?
