minus-squareDiplomjodler@lemmy.worldlinkfedilinkEnglisharrow-up37·1 month agoAny info about energy density?
minus-squareDahGangalang@infosec.publinkfedilinkEnglisharrow-up30·1 month agoAccording to Wikipedia: Looks like power to weight it much higher, while energy per volume and energy per mass is comparable to existing lithium ion batteries.
minus-squareThomasWilliams@lemmy.worldlinkfedilinkEnglisharrow-up3·29 days agoNo, the energy to volume is much less.
minus-squareDahGangalang@infosec.publinkfedilinkEnglisharrow-up1·29 days agoSee, that’s what I thought, but the wiki article seems to disagree. Or am I just misreading something?
