[–] avidamoeba@lemmy.ca 17 points 4 months ago (1 child) The packs CATL makes now are 175Whr/kg which is very close to LFP. They're already EV-worthy. permalink fedilink source parent hideshow 2 child comments replies: [–] CmdrShepard49@sh.itjust.works 2 points 4 months ago (2 children) That's great but emerging technologies are shooting for double or triple that amount, so why switch to something thats just barely reaching the equivalent potential of what's already old news? permalink fedilink source parent hideshow 4 child comments replies: [–] SaveTheTuaHawk@lemmy.ca 14 points 4 months ago (1 child) Because it's safer, cheaper and works in cold weather. permalink fedilink source parent hideshow 2 child comments replies: [–] CmdrShepard49@sh.itjust.works 2 points 4 months ago (1 child) What EVs don't work in cold weather? Cheaper for the manufacturer for sure, and potentially safer though its not as if EV fires are some major epidemic. permalink fedilink source parent hideshow 2 child comments replies: [–] phx@lemmy.world 5 points 4 months ago (1 child) At a significant loss, yes.

Winter road trips could be a pain, but that's maybe once a year permalink fedilink source parent hideshow 2 child comments replies: [–] phx@lemmy.world 1 point 4 months ago Yeah I'd be happy with a safer battery with a bit less range if it also means it's more consistent in said range between seasons. It's good to know you'll make it to X next city/charger/etc regardless of temperatures permalink fedilink source parent [–] avidamoeba@lemmy.ca 10 points 4 months ago* (1 child) I imagine vastly lower cost would be one reason. 450km range chargeable in 11 minutes would be enough for a significant proportion of people and likely desirable if the cost is low enough. I don't think it's likely that lithium would match the price/perf ratio of sodium so I think we're likely to see a lot more sodium in applications that don't require the absolute best energy density. So in a way, sodium might be the front runner, ahead of advanced lithium, in terms of what's going to be adopted. 😅 E: Also we're talking sodium batteries in production. If and when double-triple density lithium or another shows up, it might change the calculus depending on price, safety, etc. permalink fedilink source parent hideshow 2 child comments replies: [–] IchNichtenLichten@lemmy.wtf 2 points 4 months ago Exactly.
