70 Wh/Kg is indeed very low density comparing with today’s li-ion 300 Wh/kg.

Yeah but for many low-power applications, it's a damn cool development. Like I have a bluetooth keyboard and a few controllers that could eaisly fit a battery 3x-4x the current size inside no problem, so there's no need to waste lithium on that.

At 1000 times the abundancy, it is already 233 times better for stationary applications than lithium ion, no?

[–] Knock_Knock_Lemmy_In@lemmy.world 2 points 6 months ago (1 children)

Does this abundance imply 1000x cheaper storage costs?

[–] haui_lemmy@lemmy.giftedmc.com 5 points 6 months ago

Probably more like x times more profit if we cant get competition going

[–] mipadaitu@lemmy.world 13 points 6 months ago

Still great for grid storage. Save the higher density stuff for cars, trucks, and space.

[–] Cornelius_Wangenheim@lemmy.world 12 points 6 months ago

LiPo batteries are the more comparable type and are in the 140-200 Wh/kg range. For version 1.0, that's not a bad number.

That's pretty good for early production and I'm sure that will improve over time.
