Dual-fluid-layer device for reducing battery polarization phenomena

Abstract

The invention relates to the technical field of reducing battery polarization phenomena and discloses a dual-fluid-layer device for reducing battery polarization phenomena. The device comprises a casing, wherein a hollow channel is movably connected in the casing; rotating shafts are movably connected to both sides of the hollow channel; an electrode plate is fixedly connected to an end of each rotating shaft away from the hollow channel; the surfaces of the electrode plates are movably connected to a current channel; and an adjustment mechanism is movably connected in the hollow channel and includes a conductive spring. The flow distance of the current in the current channel becomes longer, so the flow speed of the current between the two electrode plates becomes slower. From the perspective of microscopic analysis, it can be understood as that the battery is intermittently discharged. Thus, the conductive spring is intermittently magnetized so as to be continuously elongated. From the perspective of macroscopic analysis, the electrolyte on both sides of the electrode plate and the electrolyte in the body are mixed with each other, thereby achieving an effect that the solution concentration on both sides of the electrode plate is the same as the solution concentration in the body.

Description

technical field [0001] The invention relates to the technical field of reducing battery polarization, in particular to a double-flow layer type device for reducing battery polarization. Background technique [0002] Battery polarization phenomenon: when current flows through the electrode, the electrode potential will deviate from the thermodynamic equilibrium electrode potential. This phenomenon is called polarization; polarization phenomenon is divided into three types: ohmic polarization, activation polarization and concentration polarization. Among them, the most influential one is concentration polarization. [0003] Concentration polarization: the phenomenon that the electrode potential deviates from the equilibrium potential due to the difference between the ion concentration of the electrode interface layer solution and the bulk solution concentration in the electrolytic cell, which is a basic form of electrode polarization; this polarization phenomenon is to hinder ...

Problems solved by technology

[0004] It is well known that the electrolyte is the medium for current transmission, and when the electrode reaction reaches a steady state at a certain current density, the concentration of the cathode interface layer solution must be lower than that of the bulk solution; while at the anode, such as a soluble anode, the interface layer solution The concentration must be higher than that of the bulk solution; both cases will cause the electrode potential to deviate from the equilibrium potential based on the concentration of the bulk solution, the cathode potential becomes smaller (moving to the negative direction), and the anode potential becomes larger (moving to the positive direction), that is Concentration polarization of the electrode occurs, but the existing battery does not have a corresponding processing structure for this phenomenon, resulting in the phenomenon of concentration polarization always exists, so a double-flow layer type equipment to reduce the polarization of the battery Came into being
