There is an insightful comment by AtlasBarfed:
Keep in mind sodium ion and LFP are much safer and don't require nearly as much cooling and management systems as nickel-cobalt chemistries: https://news.ycombinator.com/item?id=38363603 https://news.ycombinator.com/item?id=38363603
Read the whole comment, it is pretty detailed and explains why the lower density of Sodium Ion doesn't matter as much as people think.
- jillesvangurp 3y agoIt's a point that's easily overlooked. Battery density only matters in vehicles that need to be small or light (like a sports vehicle or a plane). In a truck, sacrificing a few tons for some batteries is not that big of a deal. What matters more is the price of those batteries. As those prices come down, demand will go up by a lot. That's happening right now. It's been happening for a few years now.
