The Koreans are behind the Chinese in battery technology now. Moreover, how willing would US taxpayers be to endlessly subsidise what is in effect foreign firms?
The battery manufacturing will mostly be located on American soil.
And the tax credit subsidies are guaranteed to 2030
We'll have to see what happens afterwards, but I expect some level of subsidy to continue
Ultimately the market will go to the cheapest producers who can manufacture at massive scale with speed. It is hard to know the exact cost advantage that the biggest Chinese battery producers enjoy, but I've seen numbers as high as 20%. It's the cumulative advantage of a massive, concentrated supply-chain and what is (still) about 1/3rd the wage of a South Korean, let alone a Western European or an American. Those advantages are unlikely to change even over the next decade. In other words, Chinese batteries can be replaced but only if consumers are willing to shoulder significantly higher costs. I think that is unlikely.
Yes, the Chinese battery supply-chain is the lowest cost
But the IRA means that consumers
won't have to see higher costs, because it is coming from the pocket of the US government

These are the latest Tesla pack level battery costs
Existing Panasonic 2170
$130-140 /KWh
Newer Tesla 4680
$104 /KWh
CATL
$77 /KWh
We know that the IRA battery manufacturing credit is $45 /KWh
And the current price gap between CATL packs and the Tesla 4680 packs is only $27
So future American battery plants could undercut Chinese plants on price.
If nothing changes, then the US would hands-down be the best location to locate a battery plant.
But once American battery plants come online, I do expect the Chinese (and also European/Korean/Japanese) governments to start subsidises to keep their battery plants competitive globally

And looking to the future, it's possible that battery production costs will fall to $60 /KWh in the USA. If the US government is also giving you $45 on top of that, then the batteries are only $15 /KWh
In this scenario, I see Europe, Korea and Japan all slapping anti-dumping tariffs on US batteries as well
