When I glanced at the paper in a previous posting, it mentioned cycle life on the order of 100,000 charge-discharge cycles IIRC. Saying that being a capacitor it doesn't have the limited lifetime of a battery.
Weight is simply not a significant factor for stationary large-scale energy storage. It's arguably weird to be using the same cells you'd put in a car as a "powerwall".
WRT gravity storage that's going to have moving parts and require regular maintenance like a hydroelectric dam.
- SoftTalker 3y agoI'm not sure what counts as a charge-discharge cycle, but if it happens once a day that's about 277 years. Significantly longer than any battery I've heard of, most of which are warranted in the single-digit years. On the other hand, the cement manufacturing process has high carbon emissions.
