The Tesla Model S currently has a 400-mile range, so this would represent an incremental improvement.
Personally, I can't see driving that distance without a break (at a supercharger) somewhere in the middle, so the incremental range benefit is definitely not a game-changer.
A more important breakthrough would be in cost-per-watt-hour. If we saw much cheaper batteries with the same capacity, it would go a long way toward reducing our use of fossil fuels, both in vehicles and in electricity generation.

- hcknwscommenter 6y agoThe article is light on specifics, but they link to a press release with at least a tiny bit more information. Namely, the pouch has an energy density of 900 wh/L, about twice what Tesla is using. That's huge if true. That's even bigger if there is a corresponding reduction in wh/Kg.
- memco 6y ago> The researchers say that using silver-carbon instead of lithium metal in a prototype pouch yields a battery with a higher capacity, lengthens the cycle life, and makes the battery safer. The layer of silver-carbon measures only five micrometers thick, but if it can accomplish in the real world what the Samsung team pulled off in the lab, it could substantively change EVs in the future. As others noted, it's also 50% smaller. The headline is kind of misleading the range is only part of the story.
