There are many other characteristics that make Na cells less desirable than Li and why many battery manufacturers aren't prepared to mass produce them yet. Here is a one.

Output

Na-ion: In test scenarios, Na-ion batteries have been shown to provide over 2000W per two batteries, however this is only at full charge. A fully charged Sodium-ion battery is 15.6V, and a flat one is around 10v, which means that for the same power output, the batteries need to provide 30-40% more amps when they are at a low SOC.

Li-ion: Lithium batteries will only require an extra 6% of amps for the same power output at low state of charge compared to full.
