20%+ cobalt would be LCO in the original Roadster. To my knowledge the original NCA formulations were 80/15/5 with cobalt comprising ~3.5% of total cell weight. A 2017 Journal of Electrochemistry paper analyzed 18650s from a Model S (probably 2015 or early 2016) and confirmed 80/15/5. Panasonic has likely since moved to a 83/13/4 formula with ~3% cobalt.Near the end of the clip, Baron said Telsa had "reduced the Cobalt content of the battery from 20-30% to 2 or 3%" Was the cobalt content in NCA cells ever close to 20%?
Also, he said Tesla vehicles get 4.1 miles/kWh while competitors' cars are only capable of 2.5 miles/kWh. Is that accurate?
EPA rated the Jaguar iPace at 76 MPGE, which is 2.25 miles per kWh. Model X is 2.75 and Model 3 LR-RWD almost 3.75. EPA measures from the wall plug, if you convert to miles per battery kWh (assuming 10% charging loss) you get ~2.5 for the Jag and ~4.15 for the Model 3 LR-RWD.
