Abstract

See full text

An improved electrolyte battery is provided that includes a tank assembly adapted to hold an amount of an anolyte and a catholyte, a number of cell stacks operably connected to the tank assembly, each stack formed of a number of flow frames disposed between end caps and a number of power converters operatively connected to the cell stacks. The cell stacks are formed with a number of flow frames each including individual inlets and outlets for anolyte and catholyte fluids and a separator disposed between flow frames defining anodic and cathodic half cells between each pair of flow frames. The power converter is configured to connect the battery with either forward or reverse polarity to a DC power source, such as a DC bus. The anodic and cathodic half cells switch as a function of the polarity by which the battery is connected to the Dc power source.
