Sodium Ion Battery VS Lithium ion Battery
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 0 V Among different types of batteries, Deligreen made a comparison as follows:
