And how does that work? Tesla has a standing order for any and all battery cells that can be produced by anyone, and this is the sole limit on production for 2022 and the reason another 2 gigafactories aren't breaking ground today.
How will an EV subsidy in that environment increase EV supply?
It is all about the supply chain, the certainty of offtake partnerships from the mine to the finished electrode, and the capacity to create the cells with these materials. While Elon has stated that he wants everyone to make as many batteries as possible, there have been precious few offtake partnerships with the junior miners which need the confidence and the capital to expand operations.
Take Novonix for example. They are the only US producer of qualified synthetic anode material. The best info I can find says 220 lbs of anode are needed for each BEV on average and they plan 10,000 tons of capacity online next year. That is only enough anode for around 90,000 vehicles per year. They plan to scale to 150,000 tons per annum, or enough anode for fewer than 1.4 million vehicles/year by 2030. We need much, much more production domestically and the process can scale, the feedstock can be made available, but the confidence that the finished product will be in demand and profitable when produced in larger quantities (double, triple, more?) MUST be very high to offset the additional risk associated with the accelerated expansion plans. Further, the furnaces made by Harper have long lead times and Harper also wants assurances that they will be paid. Confidence in the business model begets further confidence unlocking scale.
With this in mind, there is no known offtake partnership between Tesla and Novonix. In fact, NVX:ASX dumped 30+ percent of its value in one trading session last week when news broke that Tesla applied for an extension of the Tariff exemption under section 201 to import synthetic anode from China.
Ford, GM, VW, Toyota, Stellantis, etc. are all potential offtake partners, but as the current market sits, if you were on the board of Novonix, would you want to bet your future with a tie-up to one of these companies? The counterparty risk if (when) one of these companies goes bankrupt would prompt me to a risk-off position and I'd be more likely to maintain my current growth plans for the next few years until more information is available and my balance sheet strengthens. However, a large structural price advantage for BEV would significantly de-risk faster expansion, create increased confidence that there will be a long-term deficit in battery materials, and prompt me to accelerate expansion plans.
