"demonstrates a new sodium battery architecture with stable cycling for several hundred cycles" So nowhere near enough for grid storage (depending on their definition of "stable".)
The plot shows ~400 Whr/kg and ~800 Whr/L densities. For grid storage that is fine.
The paper https://www.nature.com/articles/s41560-024-01569-9 https://www.nature.com/articles/s41560-024-01569-9 is unfortunately behind a paywall.
We will see. Battery technologies live or die on whether the nasty, complicated surface reactions are truly reversible over discharge cycles at the sizes needed to be practical...
- gpm 2y ago400 Whr/kg is competing for the highest energy density applications that can run on rechargeable batteries. Things that fly. Cars. Not grid storage. I mean if it was otherwise suitable for grid storage it's not a downside obviously, but at those energy densities it can be inferior in terms of cost and/or cycle life and still be commercially viable in other significant markets. Not to mention this is research, it doesn't have to directly result in a commercially viable product.
