Sodium-ion batteries have started to appear in cars and home storage

That the worlds largest battery manufacturers have gone ahead with building gigawatt production plants is basicly the wake up call. They have done this based on real world deploymemt of electric cars in multiple markets over the last 3 years and of course for the main use as storage and buffering batteries, which will then allow for the full electrification of the transport sector, without putting undue strain on the,(thier) grid. this has further impact as energy costs will drop significantly, while noise and pollution also decrease dramaticaly,while increasing saftey and reiability. any country holding back is seriously fucked.
