> 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<p>Article also says it has cold weather performance improvements.<p>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.
