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.

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 (LMB)?

Novel liquid metal battery (LMB) features outstanding advantages, such as long-term stability, low cost, superior safety, scalability, and easy recycling, enabling it one of the most viable energy storage options [, , , ].

Can a low-melting-point antimony–bismuth-tin positive electrode achieve high energy density?

Achieving a high energy density still remains a big challenge. Herein, we report a low-melting-point antimony–bismuth-tin positive electrode for LMB with high energy density and excellent rate performance for the first time. The electromotive force of Li||Sb–Bi–Sn system is determined by Li||Sb and Li||Bi chemistries.

Where is a liquid metal battery made?

Bringing it to market Ambri has now designed and built a manufacturing plant for the liquid metal battery in Marlborough, Massachusetts. As expected, manufacturing is straightforward: Just add the electrode metals plus the electrolyte salt to a steel container and heat the can to the specified operating temperature.

How can battery chemistries reduce the operating temperature of LMBS?

Exploring new battery chemistries facilitates to lower the operation temperature of LMBs, and intensive efforts have been made to design new liquid alloy electrodes, molten salt electrolytes and solid ceramic electrolytes.
