Ambri, Inc. is an American startup company which aims to produce molten-salt batteries for energy storage in wind and solar power systems. In 2016 it had thirty-seven employees.
The Liquid Metal Battery Corporation was formed in 2010 to commercialize the liquid-metal battery technology invented by Donald Sadoway at the Massachusetts Institute of Technology. It was renamed Ambri in 2012. In 2012 and 2014, it received $40 million in funding from Bill Gates, Khosla Ventures, Total S.A., and GVB.
In September 2015 the company deferred plans for commercial sales of its batteries, and laid off a quarter of its workforce. In 2016 it hoped to develop a calcium-antimony battery.
In 2020, Ambri signed a contract with TerraScale to deliver a 250 MWh energy storage installation for a data center to be built in Churchill County, Nevada near Fernley.
In 2021, Reliance Industries announced that one of its subsidiaries would invest $144 million in Ambri. Reliance is also in talks with Ambri to set up manufacturing and distribution facility in India.
