November is a milestone month for Massachusetts Institute of Technology (MIT) spinoff company Ambri, where a ribbon-cutting ceremony in Marlborough, Massachusetts, on November 7 marked its new production facility. Ambri is targeting its liquid metal battery technology for use in the electricity grid. The company believes they have an electricity storage solution that will change the way electric grids are operated worldwide. Ambri's liquid metal battery technology breaks away from other storage options; 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, said Ambri. The system operates at elevated temperature maintained by self-heating during charging and discharging.
Cells are stacked into refrigerator-sized modules, placed into a 40-foot shipping container rated at 500 kW and 2 MWh storage capacity. For more energy, more systems can be deployed together side by side. The new production facility brings the team closer to their ultimate goals. "Here, we will demonstrate that Ambri's Liquid Metal Batteries can be produced at comparatively low capital cost, and make large-scale energy storage a practical reality," said Phil Giudice, CEO of Ambri.
