Sodium batteries are already commercially available and although their volumetric energy density and round trip efficiency is lower than lithium I think they are a promising alternative to lead acid and some lithium applications.
To add to the other comment - the materials are fundamentally cheaper, and so if manufacturing continues to scale they should be significantly cheaper.
Safer, very high power to weight ratio, better self discharge stability and good temperature range performance are the advantages. The most important one is of course the lack of massive environmental impact of water hungry lithium mining in dry environments and the geopolitical challenges evident in lithium sourcing.
There are a few electric vehicles with this chemistry and I predict it will replace lithium based chemistries in lower cost, smaller vehicles.
I don’t expect it so quickly, but hopefully lithium ion batteries (and variants like Li-poly, LiFePO4, etc)

What are their advantages?

Maybe in the not too distant future we will build our roofs out of solar panels and walls out of batteries.

They don’t combust when exposed to oxygen
Can you explain why and how? Do you imagine other (better?) batteries, or the disappearance of the need for batteries?
It’s definitely the former.
Yes, better batteries that don’t spontaneously combust, and last for far more charge cycles
