if you preface them as “this is completely irrelevant to the topic at hand:”, sure.

…you didn’t read the article, did you

i think the big issue is asymmetry. they charge at 3C, but they discharge at 8C. so you need the significantly overbuild.

one is energy density, the other is power density.

i think bmw was working on something like that.

from other comments it seems the energy density of batteries currently on the market is about 2/3rds that of lithium cells.

there’s also the asymmetry to worry about: with a max discharge rate of 8C but a charge rate of 3C there could potentially be limits on regen braking. if i’m understanding it correctly, sodium cells degrade quickly at higher charge rates.

idk about that, the regularly cited reason Na-ion batteries are mainly being looked at for grid storage rather than vehicle applications is their bad Wh/l and W/kg numbers compared to Li-ion. the table in the Na-ion article seems to use “1000W/kg” without a source, and it shows lithium as being about a third of that even though the Li-ion article quotes figures up to 10kW/kg.

seems the editors of the two articles aren’t cross-checking eachother.

according to their product page, the charge rate for a single cell seems to max out at 3C, which could be a pretty big obstacle to grid-scale deployment. unless that’s a problem that can be fixed with a different arrangement; i’m not too up on how to build batteries.

this is an ad.

you asked ai? cool. i asked my dog and got basically the same answer.

i had to scroll to see the last panel and it hit me like a goddamn truck

just fill in one of the o’s

i configured dyndns in my router and have it forward all traffic to a gateway vm running nginx and fail2ban. every service is on a subdomain so any attempt to fetch things from the main name gets banned.

oh right, it’s the compat thing.

oh that’s not an exploitable combination of properties at all
