I skimmed through the article. It talks a lot about sodium ion batteries and how major vehicle and transportation companies are getting into making and using these batteries. It also talks about the cost aspect, with sodium ion being cheaper than lithium iron phosphate (LFP) batteries.

However, there is no mention of this technology in consumer devices and gadgets like laptops, smartphones and tablets. I get that the site is about clean technology as a replacement for the currently more polluting technology. But I’m interested to see when these sodium ion batteries will appear in phones and laptops and what difference they may make to the cost, price, weight, performance, safety, longevity, etc.

the point of sodium batteries is that for stationary applications (e.g. ups/house backup), we've been using scaled up cell phone batteries for the last decade because the tech space was doing all the r&d. now that we know how good batteries can be, every important niche is getting it's own billions of dollars spent to find the perfect battery for that application

That's just the old Powerwall. Most home backup batteries for the last 5 years have been LFP, not Li-ion. I think even Tesla uses LFP in Powerwalls now.

that's fair. in the past 5 years or so, we've been using scaled up car batteries instead of scaled up cell phone batteries which is a lot better, but still imperfect
