Will Ambri commercialize calcium-antimony liquid metal battery chemistry in 2023?

The company plans to commercialize its calcium-antimony liquid metal battery chemistry and open manufacturing facilities to deliver projects in 2023 and beyond. Ambri Inc., an MIT-spinoff long-duration battery energy storage system developer, secured $144 million in funding to advance calcium-antimony liquid metal battery chemistry.

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.

What is a liquid metal battery?

The agreement helps secure a domestic source of antimony for its supply chain. The liquid metal battery is comprised of a liquid calcium alloy anode, a molten salt electrolyte, and a cathode comprised of solid particles of antimony, enabling the use of low-cost materials and a low number of steps in the cell assembly process.

Could a liquid-metal battery reduce energy storage costs?

Now, however, a liquid-metal battery scheduled for a real-world deployment in 2024 could lower energy storage costs considerably. Donald Sadoway, a material chemist and professor emeritus at MIT, has kept affordability foremost on his mind for his many battery inventions over the years, including a recent aluminum-sulfur battery.

Does Ambri need a steady supply of antimony?

As Ambri scales up, it will have to ensure a steady supply of antimony. Nearly 90 percent of the world's antimony today comes from China, Russia, and Tajikistan, according to Investor Intel. In August 2021, Ambri signed a supply agreement with Perpetua Resources, one of the few U.S. producers of antimony.
