Ambri's liquid metal battery technology is distinct from all other storage options on the market or in development today. It's the only battery where all three active components are in liquid form when the battery operates. The two liquid electrodes are separated by a molten salt electrolyte, and these liquid layers 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 long lifespan storage system.
Ambri achieves low cost through the use of inexpensive, earth-abundant materials and an elegant design that takes advantage of the economies of scale inherent to electro-metallurgy and conventional manufacturing.
Ambri's liquid metal battery can respond to grid 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.
Ambri's liquid metal battery technology is unique - it has distinct properties and performance capabilities. As a result, Ambri has secured a strong intellectual property position. The company has filed or has licensing rights to more than 35 domestic and international patents and patent applications and continues to pursue broad coverage.
