Embodiment Construction
[0028] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0029] As a first aspect of the present invention, an electrode is provided. Such as Figure 1 to Figure 6 As shown, the electrode includes a body 10 made of porous loose material. The body 10 has an electrolyte flow channel 11. road. Since the body 10 of the electrode in the present invention has an electrolyte flow channel 11, the penetration of the electrolyte and the electrode is more sufficient, the reaction between the two is more sufficient, and the flow path of the electrolyte is effectively planned to effectively avoid flow dead ends, thereby The reliability of the electrode reaction is ensured, thereby improving the performance of the flow battery and prolonging the service life of the flow battery. At the same time, the electrode in th...

The invention provides an electrode and a redox flow battery. The electrode comprises a body made of a porous bulk material, wherein the body is provided with an electrolyte flow channel; two ends of the electrolyte flow channel penetrate through the surface of the body; the electrolyte flow channel is an internal flow channel on the body. According to the invention, the body of the electrode is provided with the electrolyte flow channel, so that the permeation of electrolyte and the electrode is more sufficient and the electrolyte and the electrode react more fully; in addition, the flowing path of the electrolyte is effectively planned and flowing dead corners are effectively avoided, so that the reaction reliability of the electrode is guaranteed, and further the performances of the redox flow battery are improved and the service life of the redox flow battery is prolonged; besides, the electrode provided by the invention has the characteristics of simple structure and low manufacturing cost.
Description
technical field [0001] The present invention relates to the technical field of flow batteries, and more particularly, to an electrode and a flow battery. Background technique [0002] During the working process of the flow battery, the electrolyte flows inside the electrodes. As a carrier for transporting active reactive substances and electrochemical reactions, electrodes have the ability to charge and discharge. [0003] Since the electrode is the place where the charge-discharge reaction occurs, the performance of the flow battery is determined by factors such as whether the reaction between the electrolyte and the electrode is sufficient, and whether the electrolyte penetrates the electrode sufficiently. [0004] The electrolyte in the prior art only penetrates into the electrode through the pores of the electrode, so there are problems such as insufficient penetration between the electrolyte and the electrode, insufficient reaction, and dead angles of the electrolyte f...
