Reply to comment by DukeOfGeek in Salient Energy zinc-ion battery passes UL safety testing by DukeOfGeek

Tried to read up but could only find one downside, that it recharges slower. Is there any other downside compared to lithium?

Probably larger battery for same amount of storage. But if you're just bolting it to a concrete slab at a PV/windfarm that's not a big deal.

So if sieze isnt an issue these types only have upsides? Im thinking energy storage for houses, villas and departementbuildings.

The zinc batteries have a volumetric energy density of 100 Wh/L, compared to, say, 450 Wh/L for the NMC lithium battery in a Tesla. you need 4.5x as much physical space to hold the same amount of energy.

That may not be a dealbreaker for many applications. Replace a Powerwall with a dorm-fridge sized one of these in your basement or garage and you’d probably be just as happy (and happier still if it’s cheap).

Also can't burn. It's even less of an issue if you are bolting them to the ground at a wind farm where land is dirt cheap.
