  > Perhaps most significantly, the sodium-ion technology offers safety performance that far exceeds traditional lithium batteries. CATL demonstrated this through rigorous testing, including multi-sided compression, needle penetration, electric drill penetration, and battery sawing – all without fire or explosion

  Article also says it has cold weather performance improvements.

  For me at least reducing the risk of fire or explosion really nice. Sodium is obviously very accessable but not sure on other common material constraints.
