They are stable because Tesla can afford to buy them and the major OEMs are just getting started so at this point no huge problem. If VW has a sudden success with the next car, and that is likely, they'll take every battery they can get. Tesla is putting those so called low end batteries into their own cars so I'd be careful claiming there is anything different. Controlling battery supply is a great differentiator but it is very very ephemeral, in 5 years the world will be awash in batteries. Which is great. The battery advantage I see is not controlling the battery supply, which they don't, it is innovating and manufacturing excellence that enables them to roll-out things like the 4680 lines which are superior across every metric and offer a robust differentiator for the next 5-6 years. If the competition is relying on pouch batteries and slower to charge form factors than Tesla can actually offer service that matters to consumers. Faster charging, more reliability, no fires
, longer range, density great enough to offer new products such as the semi and cyber truck, etc.
I would be very careful dismissing the ability of China to dump so many li-fe-X on the market that battery supply for anyone is stable. They have in other industries orchestrated dumping on such a scale as to bankrupt whole national industrial bases- its done by providing free money to anyone starting an industry in X field- I mean any idiot could get a 1 billion dollar loan to make a factory with the only requirement that the product must be exported. Beijing may decide that's a great idea in battery and then Ford's new battery plant will be producing batteries for 2x the cost that catl or whomever is selling comps, etc etc etc. This would also impact Tesla and not in a good way. As an investor I think the question is can Tesla innovate faster than the Chinese battery guys can scale to enable dumping...that's really the race I see. Control? China will very soon pretty much control supply. Even the 4680s rely on Chinese refined inputs. Korea is trying but lacks ability to process and refine the base chemistries at scale or to produce at the scale of catl, they recognize the issue and are moving but are late; that's probably the greatest hope for actual competition. The expiration of the li-fe patents may open up all sorts of neat innovations but most likely greatest impact will be $.
If I were the new German Govt I would by hyper focused on developing excellence in battery chemistry and manufacturing. It would play to a strong EU excellence in chemistry and german manufacturing and would help save some remnants of EU auto manufacturing. I'd start by ratcheting up tariffs on all non EU produced battery and require any foreign entity to have local partners and minority ownership. Old game but that's where the EU is, basically developed world status in battery manufacturing.
