It is sad that gm essentially sold their entire "skateboard" platform they abandoned to SAIC, who now functionally own Cadillac/Buick. For all those who claim this was some kind of deception, it wasn't. Years of myopia, from the Motorola corvette to the EV-1 to the abandoned skateboard to the squandered volt and neglected bolt, GM is like Polaroid. They stopped being a "car" company and became an "engine" company, like how Polaroid stopped being a "camera" company and was a "chemical" company. This could shape up to be like JVC and its former parent, RCA, would the US gov bail them out again?

The batteries from this plant are also being used by Honda, as Honda and GM are working on sharing their BMS and platform

It will be interesting to see when sodium ion production ramps up in the US and EU. China is far ahead with this. As it was with LFP for the last few years. CATL is actually ramping up production for their second generation sodium ion battery already. They've been producing the first generation for a few years already. Sodium ion is going to be double digit percentages of the battery market in a few years. Like LFP is today. In China at least.

The advantage is not only cost but also longevity. LFP and sodium ion batteries might have decades of useful life. With thousands of charge cycles, you could be charging them on a daily basis and it would be fine. NMC only has about 1000-1500 cycles. Some LFP batteries do 3-4x better than that. Sodium ion even better.
