Ambri’s liquid metal battery technology is distinct from other storage options on the market today. Each cell consists of three self-separating liquid layers — two metals and a salt — that float on top of each other based on density differences and immiscibility. The system operates at elevated temperature maintained by self-heating during charging and discharging. The result is a low-cost and efficient storage system.
Ambri achieves low cost through the use of inexpensive, earth-abundant materials and a design that can take advantage of the economies of scale inherent to electro-metallurgy and conventional manufacturing.
In the world of electricity storage, the liquid metal battery technology performs like both a tractor and a race car. It can respond to regulation signals in milliseconds and it can store up to twelve hours of energy and discharge it slowly over time.
Liquid electrodes offer a robust alternative to solid electrodes, avoiding common failure mechanisms of conventional batteries, such as electrode particle cracking. The all-liquid design avoids cycle-to-cycle capacity fade because the electrodes are reconstituted with each charge.
Easy to Permit
The liquid metal battery operates silently, is emissions-free and has no moving parts.
