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.
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.
