What is a liquid-metal battery?
A liquid-metal battery, developed by Ambri, consists of three liquid layers stacked together based on density. The densest layer, 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 a liquid metal battery (LMB)?
The liquid metal battery (LMB) is an attractive chemistry for grid-scale energy-storage applications. The full-liquid feature significantly reduces the interface resistance between electrode and electrolyte, endowing LMB with attractive kinetics and transport properties. Achieving a high energy density still remains a big challenge.
Are lithium-antimony-lead batteries suitable for stationary energy storage applications?

What makes liquid-metal batteries resistant to capacity fade?
The liquid-metal battery’s lower cost arises from simpler materials, chemistry, and system design compared to lithium-ion, and its longer lifetime, says Sadoway. “The concept of a liquid-metal battery makes it unique for stationary storage. It’s not flammable, unlike lithium. And it’s resistant to capacity fade.
