Tesla going into lithium mining and cell production is absolutely necessary IMO but presents multiple challenges:
- According to my calculations, Tesla will very soon need all 35GW. Tesla vehicles would require 55GW in 2020 and 100GW in 2021.
- Most probably, the Panasonic agreement is being renegotiated. I believe they are working on an outright purchase of the business wiping off the obligations.
- Cell manufacturing is a high CAPEX low return according to Maxwell and Panasonic financial statements.
- Going further down the supply chain increases the CAPEX per vehicle while probably reducing the cost per vehicle, will significantly increase inventory of unfinished products (Working capital). It will also reduce Accounts Payable because Tesla is its own supplier.
- Tesla plan to replace Panasonic seems to add multiple steps: Lithium feedstock mining and shipping, processing it to battery grade lithium, source all other cell components, create the cathode, and finally create the cells. The cashflow cycle will ultimately depend on shipping and manufacturing lead times.
- Tesla might need to access the capital markets again feeding the shorts narrative.
- TESLA most probably had a full-scale plan prior to the decision to acquire Maxwell (Dec 2018). As I mentioned the 35GW will be reached by year end, and I expect the Battery Investor Day to be very soon.
- I would be surprised if Tesla did not already provide Tesla Grohmann with an R&D budget to create a much faster cell production line.
- There is a slight probability that the Boring Company might disrupt the traditional cost structure of rock mining.
- Unlike battery manufacturing, it seems from public filings that lithium mining has good ROI.
Pretty sure Panasonic and/or Tesla is sourcing cathodes, anodes, lithium, and aluminum (or was it steel?) for the cans from other companies already. So they don't have to insource those all at once to replace Panasonic, to replace Panasonic they just need to hire all the same suppliers to supply them, and replace the special sauce (of which they already know much from being involved in it) of the electrolyte chemistry (which again, in part is supplied from outside likely, with just the method of mixing it together and ratios and such being proprietary), and the actual manufacture of cells from these parts (cans, anodes, cathodes, electrolytes).
So they might eventually insource some of these other aspects (i.e. lithium by becoming a mining operation) but if they're replacing Panasonic they only have to replace Panasonic, not the entire supply chain.
