Interesting but I will wait till these hit the commercial market and whether or not they meet expectations before praising.
Also, if these things aren’t made to be economically recycled it’s just more e-waste heading to the landfills.
Well if you are going to landfill something, glass/ceramics,salt,aluminum foil and plastic bag is not something we don’t already landfill by the millions of tonnes per year in municipal landfills.
These cells will have no heavy metals, no toxic or corrosive liquids, the sodium is in ion form probably a salt or carbonate, cathode is carbon based , or silicon carbide or carbon, could be Prussian Blue or white both of those are carbon,nitrogen and iron based. The blue is what makes blue jeans blue btw it’s a water soluble dye.
The market will determine if it’s worth it to recycle the materials or not. We don’t recycle alkaline batteries as is now and those have caustic liquids in them they are thrown away by the billions of individual AA and AAA per year full of manganese , zinc and aluminum and copper too. It’s simply cheaper to mine more and landfill the old ones no one blinks at it. How many smartphones do you throw away per year? Tablets and laptops too. That the market we are talking about. Large packs will be regulated simply because of the dangerous voltages involved you will never landfill a EV sized pack those will have to be disassembled and safed the individual cells might be landfilled but if you took them out you can now easily grind them up to black mass and leach the metals out cheaper than mining and processing them for sure copper and probably aluminum too the salt is well salt it’s dirt cheap literally.
