Sodium Ion Battery VS Lithium ion Battery

2024-06-12 18:17:25 Deligreen 1033

Sodium ion battery is a hot topic nowdays.

There are many types of batteries such as Lifepo4, NMC, lead acid battery ,solid state battery and so on.

What  are the differences/ advantages of sodium ion battery?

1)Na+raw material cost 50% lower

2)sodium salt conductivity is about 20% higher than lithium electrolyte

3)Zero risk of over discharge:

 it is allowed for sodium ion batteries to discharge to zero volts

4)High energy density above 120wh/KG

Why sodium ion battery is safer?

1)lower current during short curcuit and less heat since the inner resistance is high

2)Na+ are more stable in aqueous solutions,

3)high activity ,can avoid battery short circuit self ignition

4)no fire no explosion

5)Sodium ion battery can be over discharged till 0V

Among different types of batteries, Deligreen made a comparison as follows:
