I've been hearing about these for a few years now. Huge if they work out at a large scale.

The comment I am responding to is about charge rate, not discharge rate

For most batteries that's the exact same rate

Sodium ion batteries are asymmetrical, pushing charge current hard can drive the anode negative enough to deposit metallic sodium causing formation of dendrites which destroys the battery. Discharge is not limited by the same mechanism
