I don't know about that. The Tesla developed 2170 battery is exactly what the electric car world needs. It contains no Earth shattering new battery technology. Instead, it's a well refined and up-sized version of the common 18650. Those details matter, immensely. As maximum current flow is doubled, energy capacity is increased by 50% and total cell count is reduced. Much of this is due to simple geometry. As the new 21mm x 70mm case contains 35%-50% more "battery" inside, while being only a few mm's larger outside. Internal heating is reduced, and lifespan is greatly increased.
We'll see.
