Abstract

The invention discloses a detachable three-electrode battery testing device and an assembling method thereof. The device comprises a shell, a lead screw, an extrusion assembly and a reference electrode assembly, wherein the shell comprises a base, a first sealing ring and an upper cover; a positioning groove is formed in the cavity bottom of the base; the upper cover is detachably connected to the top end of the base; the first sealing ring is arranged between the upper cover and the base; the lead screw penetrates through the upper cover and the first sealing ring to be in threaded connection with the base. The device can test and research the impedance and the change condition of the electrode plate, can research and analyze the dynamic mechanism in the chemical process of the electrode, can judge and analyze the battery capacity recession reason, is high in sealing performance, avoids air leakage and liquid leakage, can realize thousands of cycles of a power or energy storage battery, improves labor efficiency, the device is simple in structure, reasonable in arrangement, low in cost and high in practicability, and the assembling method is safe, few in step and easy to operate.

Description

technical field [0001] The invention relates to the field of battery testing, in particular to a detachable three-electrode battery testing device and an assembly method thereof. Background technique [0002] Due to the advantages of small size, less material consumption, low cost, relatively simple assembly, and easy testing, two-electrode button batteries are widely used as the main evaluation method for battery positive and negative electrode materials. However, there are also obvious defects and deficiencies in the analysis and research of two-electrode button cells for electrochemistry, mainly in: 1. It is impossible to test and study the impedance of the electrode sheet itself and its changes, and it is impossible to study and analyze the chemical process of the electrode The dynamic mechanism in . 2. Unable to judge and analyze the cause of battery capacity decline. In fact, the end of battery life and capacity decline are often only caused by one of the electrodes ...
