6 Frequently Asked Questions about “Liquid Metal Antimony Battery Production Process”

Could antimony be a viable alternative to a liquid-metal battery?

Antimony is a chemical element that could find new life in the cathode of a liquid-metal battery design. Cost is a crucial variable for any battery that could serve as a viable option for renewable energy storage on the grid.

Can antimony be used as a battery metal?

Antimony is key for the transition to a low carbon future. As a glass clarifier in solar panels or as a metal strengthener to wind turbine components, antimony plays an important role in producing clean energy. More recently, antimony is gaining recognition as a battery metal for its role in “liquid metal battery” technology.

What is a liquid-metal battery?

Ambri's liquid-metal battery consists of three liquid layers stacked together based on density. The densest, a molten antimony cathode, is on the bottom, the light calcium alloy anode is on top, and the intermediate-density calcium chloride salt electrolyte sits in the middle.

What is Ambri's liquid metal battery with antimony?

Ambri's liquid metal battery with Antimony makes the transition to a 100% renewable energy grid possible. Watch our webinar to learn more about antimony and the critical role it plays in America's energy, technology and defense future.

Is antimony a key mineral for a low carbon future?

Yet, with no domestically mined source and an unstable supply, the U.S. Department of the Interior has deemed antimony as one of the 50 critical minerals. Antimony is key for the transition to a low carbon future.

Are lithium-antimony-lead batteries suitable for stationary energy storage applications?

However, the barrier to widespread adoption of batteries is their high cost. Here we describe a lithium–antimony–lead liquid metal battery that potentially meets the performance specifications for stationary energy storage applications.
