Full breakdown of Tesla's Battery investor day. From the new 4680 cell, to the tabless electrode,  to the potential of the Model 2 ... I try and summarize one of the most important days in Tesla history. The cat is out of the bag, Tesla is bringing cell production in house and scaling like crazy. They plan to hit 100GWh/yr by 2022 of this new cell. That's triple Tesla's 2020 battery consumption. This implies Tesla is getting ready to sell Ms of vehicles per year.
