At this fast pace of expansion, how is BYD's quality control? How about their cars fit and finish standards?
As far as I can tell, BYD standards are still very high.

So here is the dilemma facing any auto manufacturer in China. There seems to be unlimited demand for EVs. Therefore, you want to increase your production rate as quickly as possible. But everyone else is doing the same. So at the end of the day, you have to delay delivery if you cannot ramp up to the numbers you were hoping for. As impressive as BYD's June production was, it's still lower than what they planned for in the optimistic ramp up. As such, customers are facing long delays and placing orders with Huawei or legacy ICE cars. At this point, I'd be very concerned about Huawei if I were BYD.
Anyhow, on to battery front. It seems to me China has selected LFP as the type they want for energy storage.
Sodium sulfur batteries operate at high temperature, so there are inherent safety risks there. They use sodium metal as well, I'm sure you remember the high school chemistry demos where the teacher dumped a lump of sodium into a beaker of water.Why has LFP been selected over sodium for storage?
Maybe internationally. I think Tesla is getting increasingly uncompetitive in China due to its lack of investment in smart driving. Long term, there is really not many players who can potentially compete against BYD in power chips, autonomous driving, electric train. They can always use CATL batteries and get a bunch of struggling/start up manufacturers to use their technology.My read is that BYD should be more concerned with Tesla than Huawei
No question Sodium-ion battery would work also. At this point, I'd say LFP is quite far along in commercialization. Even though sodium-ion battery should be cheaper than LFP battery in terms of materials, all the LFP factories that have already been built points to lower cost/higher volume LFP energy grid storage for a while. If you look at something like this.I read that as a negative list against Ternary or sodium-sulphur batteries.
For grid-storage, I would expect Sodium-ion batteries to be preferred over LFP. They might only be half the cost. But assumes sodium-ion batteries are available in large quantities.
It'd take a while for sodium-ion batteries to gain market acceptance. At this point, LFP energy storage's main competitor is still ternary batteries.

Sodium ion batteries are very different, they operate analogously to lithium ion batteries. Already CATL's first generation sodium ion batter has specific energy density comparable to LFP. Better yet, its anode and cathode materials are readily available - charcoal and an easily produced organic compound. Grid storage is a very promising application for them; I consider lithium too valuable to waste on something like grid storage.
