Thank you for the videos. Battery chemistry/cost etc. are not my areas of expertise, so I rely on my reading of expert opinions here and elsewhere for this. So I encourage others to chime in. I think
@techmaven has pretty good info on this.
For future reference: if my sentence/post starts with "my understanding is..." that means I'm less than 90% confident on the rest of the sentence, but confident/curious enough to share and start a discussion.
Because of limits to my understanding on this subject, I'm inclined to be conservative on how much cheaper Tesla's battery pack cost can get (i.e. not much further below $100/kWh) as well as how many years before competition catches up to Tesla's cost per kWh (~3-5 years as others will need to build gigafactories). Even with this, investing heavily in TSLA makes sense for me, as more data becomes available and I expand my knowledge on this matter.
Keys to my thinking on this:
1. Tesla/Panasonic partnership has led to leading technology (combo of lower cost and better energy density) that is not easily replicable
2. Gigafactory-level scale is necessary to compete with Tesla on battery cost per kWh
3. Battery cost per kWh is a primary component of gross margin
4. Tesla is at the forefront of research, via its leading team of engineers as partnerships with Jeff Dahn and others, that may lead to better tech
I would encourage anyone to argue against any of the above.
