Well aware of LFP. The device I’m using now was charged by it. The problem is that grid storage needs tremendous scale, and for that lithium battery chemistries are constrained by lithium extraction. Sodium is already abundantly available
- xbmcuser 2y agoI was bullish on sodium ion batteries last year but now I don't see them taking off at least for the next few years unless sodium ion tech is 40-50% cheaper today. The reason being no matter how much oil and gas companies keep harping about lithium shortage reality is lithium production is likely to stay ahead of demand for the next few years. And the incremental improvement in lithium battery tech and production each year keeps sodium ion tech from keeping any cost advantage.
- h0l0cube 2y agoLast I checked they were always on par for household energy storage units, leave aside grid scale. If this is their starting price before economies of scale really kick in, then I can’t see what the next couple of years bring. Esp. as new grid scale batteries are coming online. There’s still more innovation to do in terms of improving cycle life though
