Abstract

An embedded electrode frame of a flow cell pile belongs to the technical field of flow cell manufacturing. The embedded electrode frame is characterized in that a first bipolar plate frame (5) used as a positive pole half-cell of a single cell, a second bipolar plate frame (6) used as a negative pole half-cell of another adjacent single cell and a bipolar plate (9) clamped between the first bipolar plate frame (5) and the second bipolar plate frame (6) are connected sequentially to form an electrode frame (4). The first bipolar plate frame (5) and the second bipolar plate frame (6) achieve accurate location by means of a mutually embedded structure formed by a boss and a groove. A sealing ring groove provided with a sealing ring is arranged on the surface of the electrode frame which are formed by the first bipolar plate frame and the second bipolar plate frame, the sealing ring groove locates on the combined surface where the boss and the groove are in clamping connection to facilitate installation and sealing, and the flow cell pile is formed by connecting a plurality of electrode board frames.

Description

technical field [0001] An embedded electrode frame of a liquid flow battery stack belongs to the technical field of electrochemical energy storage, in particular to a technical method for manufacturing an electrode frame of a liquid flow battery stack. Background technique [0002] Using renewable energy such as wind energy and solar energy to generate electricity is one of the important ways for human beings to obtain energy from nature in the future. Due to the randomness and discontinuity of the wind and solar power generation process, it is difficult to maintain a stable power output. It needs to cooperate with a certain scale of power storage devices to form a complete power supply system to ensure continuous and stable power supply. Therefore, the development of energy storage systems with high power conversion efficiency, large storage capacity, and good economic performance has become the key to the development of renewable and clean energy. Among various forms of e...
