Sodium solid state, I love where this is going.

Chlorine-Based Sodium Solid Electrolyte
Publication number: 20230115956
Abstract: Sodium-based all solid-state batteries exhibit improved battery cycle life and stability with the use of a new chloride-based sodium solid electrolyte in which sodium diffusivity within the electrolyte is enhanced through substitution of atoms including one or more of Y with Zr, Ti, Hf, Ta, and Na with one or more of Ca and Sr.

“In the case of the sodium-oxygen cell, the proton phase catalyst transfers the newly formed sodium superoxide (NaO2) entities to solution where they nucleate into well-defined nanocrystals to grow the discharge product as micron-sized cubes.

The dimensions of the initially formed NaO2 are critical; theoretical calculations from a group at MIT has separately shown that NaO2 is energetically preferred over sodium peroxide, Na2O2 at the nanoscale.”

Definitely, investing.
