Liquid electrode battery

摘要

An electrochemical battery that exchanges energy with an external device. The battery includes a container (22) having walls and containing a positive electrode (16), a negative electrode (14) and an intervening electrolyte (20), the electrodes and electrolyte existing as liquid material layers in a vertical stack within the container walls at the operating temperature of the battery. One of the positive electrode (16) and the negative electrode (14) is disposed over the electrolyte. A lid (26) closes a top of the container (22); a positive current collector (23) is in electrical contact with the positive electrode (16); and a negative current collector (27) is in electrical contact with the negative electrode (14). Positive and negative current collectors (23, 27) are adapted for connection to the external device to create a circuit through which current flows. The current collector is in contact with the one electrode is suspended from the lid (26) and comprises a structure (62) configured to hold one of the electrodes away from the walls of the container.
