Antimony: The Most Important Mineral You Never Heard Of, page-3

If you want to understand more as regards liquid metal batteries, I suggest you visit the Ambri website: https://ambri.com/

It is very exciting technology and will shortly be installed in a commercial scale power storage facility in the US. This technology has the potential to displace Li ion batteries from power storage facilities as it is much better suited on all fronts. There is an argument that Li ion is a transitional battery technology for power storage and will be displaced by the next generation of battery technology such as liquid metal in power storage applications

Definitely a technology to watch (and new use for antimony).
