• Don Sadoway's liquid metal battery

    From Bob F@21:1/5 to All on Wed Jul 10 16:33:42 2019
    Grid scale battery scheduled for 2020.


    Ambri will be commercializing a utility-scale liquid metal battery
    within three years. In 2020, they want 10-foot cube commercial units in proof-of-concept field deployments.

    Ambri’s liquid metal battery was initially based on magnesium and
    antimony as the negative and positive electrodes and a low-cost molten
    salt electrolyte. Ambri has transitioned to using a higher voltage and
    lower cost chemistry.

    They halted commercialization because of a problem with the seals on its high-temperature battery cells. They restarted with the new, lower-cost chemistry.

    Utility battery storages projects are currently scaled for the 4-hour
    duration. Ambri is targeting 4 to 12 hours of duration.

    The base unit for Ambri’s system is a fully-sealed liquid metal battery
    cell. Ambri’s cells are connected in a thermal enclosure to form an
    Ambri Core.
