Hard. Batteries are unavailable in required quantities, and extremely expensive to spool up. Doing so would make most of their existing factories and tooling worthless assets. (They will be anyway, just unwilling to make the transition proactively, and likely be a tiny shadow of their former selves)

Most people don't realize this. Even Panasonic, which is the most experienced and produce most of the Li-ion batteries today is still struggling to expand their GWh capacity.

The global lithium-ion battery market is expanding at a CAGR > 25%. Hardly a struggle.

Not all li-ion batteries are the same. They have to be a certain chemistry and form factor.

With cylindrical (18650) being the most common that Panasonic manufactures. Because they can be produced quickly, hence the lower cost per kWh. They are also a Tier 1 lithium-ion battery producer. Meaning they produce the highest-quality lithium-ion batteries, for automotive use.

Samsung and LG Chem are also Tier 1. But Panasonic is certainly more mature and have more experience (but more conservative like Toyota). Which I already mentioned earlier.

That is the fastest they can go, while EV vehicle demand growth exceeds that CAGR. When the 3 industry titans can only together drive ~15-20% annual growth, it is most definitely a struggle.
