Go Big or Go Home! Massive new batteries.

This is a cool piece of technology I thought would be cool to share. These cells could really change energy density very soon!
Panasonic revealed their own 4680 batteries late last month. The monster (46mm dia. by 80 mm long) have 5x the capacity of current 2170 cells. Test cell production is slated for March of 2022 and Panasonic is investing heavily in new lithium technologies, and we could see more from them soon.
It will be great to see when these devices trickle down into complete battery packs and regular OEM's can purchase them. It will be interesting to see if one 4680 cell is over 5x the cost of 2170 cells, or if there will be large a decrease cost per kWh.
Tesla unveiled their version of a 4680 cell several months ago. Tesla had some cool concepts on solving some of the electrical path and chemistry issues common to a large battery. The picture below shows Tesla's tab-less design to overcome electrical path issues. It is a cool picture to just stare at like a shell. It will be interesting to see how Panasonic solves the same issues.
