I didn’t see it in the article, but do they have a comparison in terms of energy density vs alternatives? What niche are they trying to fill?
Environmentally friendly batteries are exciting, just trying to gauge how excited I should be.
I wonder how big it is to physically deliver (only) 1.25 V at a capacity of 110 mAh. This won’t be powering much of anything in the near term. Also I’d be curious, as they claim it being water and organic matter based, if we could just “drain” the existing battery quickly and load in new pre-charged fluid to quickly recharge (I.e. recharge an EV as quickly as a gasoline based vehicle).
That would be huge!
For this, of course, it matters a lot how energy dense the battery is. Also for the environmental impact. If I have to exchange three gigatons of liquid for my trip to the grocery store, a rolling coal truck might have the smaller footprint.
110 mAh/g * 1.25 V * 1000 g/kg = 137 Wh/kg.
Lithium ion is around 250 Wh/kg, so this battery is around twice as heavy.
Seems like a decent option for stationary energy storage then.
