At a risk of stating the obvious, here's how I see the balance of forces going forward.
Battery's value is in storing energy. Battery is raw materials plus the cost of transforming those into a battery.
Tesla is attacking the problem on both fronts. If someone can produce a 10% better energy storage using the same amount of raw materials, they're effectively getting a 10% raw materials discount over competition. If someone can produce the same battery 10% cheaper than competition, again not much competition can do since it's a commodity market.
Now there's an extra twist that specifically for automotive applications the 10% better energy density is translating to possibly more than 10% overall vehicle performance or price advantage over competition. This doesn't hold true for stationary storage, but for automotive applications battery size, weight and capacity has "leveraged" influence on the overall vehicle.
In an interview a couple of years back Elon was asked about the almost weekly announcements of battery tech breakthroughs and how we seem to never hear about them again. Elon said that if someone comes up with a better battery, they'd love to know about it and they'd buy more of them than anyone, but Tesla is using the best battery chemistry available for the application. When something better comes along, they will switch to it as soon as it proves viable.
People got used to electronics evolving at the pace of Moore's Law. It's tapered off now, but Moore's Law held for most of the lifetimes of the people on this forum. (Moore's Law was stated by one of the founders of Intel Gordon Moore who predicted that the density of what could be put on silicon could double every two years and the price to do it would be cut in half.) People kind of expect all electronic innovation to follow Moore's Law, but most things don't work that way.
Battery tech has been frustratingly slow to evolve. For rechargeable batteries all we had for most of a century were lead acid cells. NiCad came along in the 70s and it was an amazing innovation. Li-ion was discovered by accident and is more a class of battery chemistries than any one chemistry, but there are about 7 different variables that need to be balanced for any battery chemistry and finding anything that is an improvement on what we have today is very difficult.
And the Chinese are not the leaders in any area of fundamental research. They are decent engineers, but most Chinese scientists who want to innovate find more freedom to do so in other countries. The Chinese are good at capturing ideas spawned in other countries that didn't go anywhere for one reason or another and making them happen. But they are not leaders in battery chemistry. Most of that work is being done in Europe, North America, and some in Japan and South Korea.
With battery chemistry breakthroughs there is at least one western company: Tesla who will actively go for any advancements in chemistry that works for their applications, so the Chinese are not going to get a jump on the west the next time there is a battery chemistry breakthrough. The only situation where the Chinese might get a jump is if the discoverer of a new chemistry goes to the Chinese first, but that's probably unlikely.
Battery tech evolves very slowly. There are billions being poured into the next generation of battery chemistry, but we have had very little advancement in chemistries best for EVs over the last 10 years. Tesla started adding a little silicon, but that's about the only change from the original 18650s Tesla used for the Roadster. There are rumors the 2170 will use a new chemistry, but I haven't seen any confirmation of that.
The batteries have become cheaper to manufacture in small increments, but rather than the 50% reduction per 2 years with Moore's Law, it's only a few percent a year.
The only way anybody beats Tesla at this point is Tesla makes some huge mistake, or rests on their laurels. Neither of which are likely.
Stationary storage, even though energy and specific density of the battery isn't so important, Tesla+SolarCity has another competitive advantage in this field: they have an integrated solution, including a sophisticate software package, solar, inverters, etc.
So from what I can tell, for competitors to take Tesla on:
- in the stationary storage commodity market (when it matures) they'll have to match Tesla's manufacturing efficiency (scale+optimized production), and product integration.
- in automotive, they'll have to match Tesla's manufacturing efficiency AND Tesla's pack-level volumetric and density parameters.
Tesla has some edges here, but probably less than they do with car tech. With stationary storage, there isn't as much of a space concern and lower density, cheaper batteries may make a decent alternative. Though for home use, compact is often better. A power station can use up a half acre with batteries, but the home user isn't going to go for a battery that requires losing a parking space in their garage, or equivalent.
We may see the stationary storage go like calculators back in the 1980s. If you wanted the best bar none, you bought an HP, but they were also expensive. Most people went for something cheaper, but wanted an HP.
My personal opinion on the subject is that I don't see an
organization that can do this. Elon and JB's
INTJ character and engineering talent creates an integrated approach that can't be matched by a traditional hierarchical org structure with a professional manager at the helm. The fusion of car design and factory design is a prime example: a traditional org would never do that since that would jeopardize established areas of influence and challenge status quo of major stakeholders.
I haven't seen anyone else reference Myers Briggs here. When I did a while back I got scoffed at. I'm not sure about JB's type, but from Elon's biography I think it is likely he is an INTJ, though only he could say for sure.
