Kristin Brief


AMBRI is an early age storage startup company based in Cambridge, MA. The liquid Metal Battery was invented at MIT in Professor Donald Sadoway's lab. Ambri's goal is to create a cost-effective, reliable, grid scale battery technology that will facilitate full integration of intermittent renewable generation like wind and solar, relieve grid congestion, reduce the need for power plants, transmission and distribution infrastructure, and thereby reduce the cost of electricity for all.

More Details

Ambri’s investors include Khosla Ventures, Bill Gates, Total, KLP Enterprises and the Swiss insurance company, GVB. To date, Ambri has raised more than $50 million in equity financing. Ambri’s storage technology is unlike anything that exists in today’s market. It is the only battery where all three active components (anode, cathode and electrolyte) are in liquid state when the battery operates. We are on a path to commercializing the world’s first and only stationary storage system that is simultaneously:
1. Low cost 1/3 to 1/2 the cost of today’s commercial systems; every $1 of capital invested in an Ambri manufacturing plant will provide 300 to 600 percent more storage than $1 invested in lithium-ion manufacturing
2. Long lifespan  demonstrated fade rate is 0.0002% at 100% depth of discharge which implies our batteries will last for more than a decade with negligible fade; minimal maintenance required
3. Safe  active ingredients are held in 1/8” thick sealed stainless steel cell can which provides over a 1000°C temperature tolerance range between battery operating temperatures and steel’s melting temperature; solid and completely inactive at room temperature
4. Operationally flexible  with 80% DC to DC roundtrip efficiency and near instantaneous response rates (depending on power electronics); Ambri’s LMB technology can support a broad range of grid storage applications, including both power and energy
