Imagine a battery that laughs in the face of fire hazards while cutting energy storage costs by 90%. While lithium-ion batteries have been hogging. From Energy Storage News– 'Liquid metal' antimony based battery technology developed as a potential low-cost competitor for lithium-ion looks set to be used at a data centre under development near Reno, Nevada. The pioneering technology originates from the startup Ambri, which plans to introduce a system with a capacity of 300 kWh in Aurora, Colorado. This. Ambri, a US long duration energy storage (LDES) company, has partnered with Xcel Energy (US utility holding company) on a demonstration project. Together, Ambri and Xcel Energy, will install a liquid metal battery in Colorado in a grid-connected scenario to prove the ability of calcium-antimony. Antimony is a chemical element that could find new life in the cathode of a liquid-metal battery design.
