They did, Tesla was the first to invest into Gigantic battery production and winning with economy of scale and vertical integration.

That was until China has more electric vehicles sold than rest of the world combined. They made 95% of all electric buses in the world. So the economy of scale somewhat shifted. And the rest comes with continual investment.

You seem to have missed the bit about Panasonic building all the cells.

They are buying the same batteries currently, but are scheduled to announce an important battery breakthrough sometime this month at "Battery Day". According to leaks, this is known as project roadrunner inside Tesla.

They have some unique new patents on battery tech like this one: https://patents.google.com/patent/WO2020082019A1/

A single crystal cathode significantly reduces stress as it has fewer seams. This video provides a great explanation if you're interested in the technical details: https://www.youtube.com/watch?time_continue=11&v=dpe-ajzucTE

I think Tesla has more mature battery management software that prolongs the life of the battery but that may no longer be true or exclusive.

Lucid also has quite a bit of data collected from Formula E that should help with battery management.

It's both. They are buying batteries from suppliers in China in order to keep up with demand, but they are also working closely with Panasonic on the chemistry for the majority of their batteries. In addition they are directly funding and performing in-house research on next generation battery chemistries. We also don't have many details about this new CATL battery. Almost all Li-ion batteries are capable of lasting a million miles under the right conditions, so the devil is in the details. A true million mile battery will be able to last a million miles under most real world conditions, which hopefully both this CATL battery and the Tesla million mile battery will be able to do. I think Tesla might have a bit of an advantage there since they control the whole stack, but we will have to see.

"winning with economy of scale and vertical integration"

Might have been written by a bot.

Note that although Panasonic is technically building them, they are doing so inside the Tesla Gigafactory in Nevada. Panasonic wasn't able to deliver the gains that Tesla wanted which strained the relationship and led to Tesla's decision to manufacture cells independently.

“He claims his Hyperloop concept could revolutionise public transport.” Hyperloop is private transport.

Random question: is Hyperloop all just a ruse so Elon can develop expertise in boring through martial soil and creating vacuum sealed tubes?

Formula E is very limited compared to 1000s of cars in all condition with all driving patterns.
