What are their advantages?
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.
They don't combust when exposed to oxygen
To add to the other comment - the materials are fundamentally cheaper, and so if manufacturing continues to scale they should be significantly cheaper.
Maybe in the not too distant future we will build our roofs out of solar panels and walls out of batteries.
