There have been several tear downs of Tesla battery packs i was just looking at two in particular, both from Electrek, one from Jan 2017 of a 100 KWH pack and the other in Feb 2016 of the 85 KWH pack (both are obviously 18650 cells) so here's what I found.
85 KWH Pack:
80.7 KWH actual
11.4ish watts per cell
100 KWH Pack:
102.4 KWH actual
12.4ish watts per cell
one year apart the cells haven't changed size so the chemistry must have improved by about 9 percent, that's freaking awesome (not to mention all the other improvements). This just makes me even more excited about the possibility of the 2170 cells being even more chemically/energy dense, bigger, and better. what do you guys think? Did I miss something?
