Anode chamber of a dual active material battery

Abstract

The invention discloses an anode chamber of a dual-active material battery, which comprises a diaphragm I located on the outermost side, a current collector is arranged inside the diaphragm I, and the area inside the current collector is filled with an electrolyte, and a metal energy storage material is arranged in the electrolyte, and the current collector It is connected with the metal energy storage material through a conductor, and a redox couple is arranged in the electrolyte near the current collector, and the metal energy storage material is arranged in the electrolyte in the inner area of ​​the diaphragm II. The invention provides an anode chamber of a dual-active material battery. This anode chamber structure utilizes the advantages of the high energy storage density of aluminum-magnesium metal materials and the advantages of liquid-phase reducing agent and high power density of zinc anode to form a composite anode chamber. , this anode chamber can form a metal-air battery with an air cathode to increase the power density of the metal-air battery; it can form a metal semi-flow battery with the cathode of a flow battery to increase the energy density of the flow battery.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to an anode chamber of a double active material battery. Background technique [0002] Existing liquid flow batteries have high power density but low specific energy. Existing metal-air batteries have high specific energy but low specific power. In addition to the air cathode polarization, another important reason for the low specific power of metal-air batteries is due to It is necessary to replace the metal plate with a larger gap between the cathode and anode, resulting in higher internal resistance and lower specific power. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides an anode chamber of a battery with dual active materials. [0004] The purpose of the present invention is achieved in the following manner: [0005] An anode chamber of a dual-active material battery, comprising a first diaphragm located o...

[0002] Existing liquid flow batteries have high power density but low specific energy. Existing metal-air batteries have high specific energy but low specific power. In addition to the air cathode polarization, another important reason for the low specific power of metal-air batteries is due to If the metal plate needs to be replaced, a large gap must be set between the cathode and anode, resulting in high internal resistance and a decrease in specific power
