I thought we were moving to sodium!
- Sodium-based batteries currently have a lower energy density than lithium-based batteries so they are only useful in some applications.
  
  Mainly for cheaper applications which are not as weight (and size) sensitive. One example is entry level EVs or home energy storage.
  
  Oh.
It sounds like they need to do a lot more work to increase the cycle life.
- That's usually the problem with these ultra high capacity batteries. The electrode structures just don't hold up
