After watching a bunch of follow up videos on battery day and having a bit more time to think about the updates - doesn't the tabless electrode now seem so obvious that all previous batteries sound stupid. There is just so much to be gained from amending a relatively simple manufacturing technique rather than all the time, experimentation, supply chain consequences, etc. required to muck about with cell chemistry changes.
The whole purpose of a battery is to shift electrons from one electrode to another in a process that creates heat as a side product - and up until now every battery maker has decided to hinder this process by forcing all the electrons to go through a tiny funnel and then travel a long distance through the electrode - constricting electron flow and heat removal while increasing heat generation.
The implementation, which is very clever, surely should have been figured out by the traditional battery makers previously. Ultimately it is just a relatively minor change to the way the electrode backing is cut and rolled. Instead of making this change people have poured billions into expensive and inefficient thermal management systems to try and solve the heat issue.
It's got to be the brilliant people and culture at Tesla that allowed them to figure out a game changing tech like this when it should have been staring all the professional battery makers in the face.
I think the point is that indeed it's not a new concept, it's already used on larger batteries, but Tesla are the first to be able to make it work with this form-factor = they are way ahead in engineering capability compared to the rest.
