Here we go again. Samsung is adding silver to lithium to surpress dendrite growth. There is not enough silver in the world for this. Still for a mission critical battery it makes sense.

Is silver the sacrficial material, or is it plating to increase electrical properties?
The plating is to stop dendrite growth. This could still fail.

Trying to make it function as a conductor, but it works like a diaper instead…lol. i guess in an anaerobic invironment, the silver won’t tarnish. And assuming the silver retains its conductive properties and doesn’t instead function as an insulator/capacitive layer.
I wonder how much silver per cell is needed. If it’s just plating, then maybe it’s negligible

The United States has just declared silver to be a stratigic mineral. That is they can stop the sellers from selling to any one else but the government. China has express an interest in Samsung batteries and it may take 2 kilograms per automobile.
Post links, looks like it might be an interesting read
This talks about the batteries 12.20.25: SILVER Electric Vehicle announcement will increase DEMAND, Prepare for major increases in
The video and most other data I’ve found says 0,6-1kg/100kWh, so much lower, but still quite an impact. Add to that the fact that world silver production is at about 26000 tons, so 26m car worth’s, totally unfeasible. I’d guess they’ll search for substitutes stat ^^
OTOH, a kilogram of silver is ~2000USD, not much considering the supposed benefits of such a battery (600miles, 20 year lifespan, below 10 minutes for 80% charge). Would make EVs much closer in usability to gas cars, assuming charging infrastructure is there
