A three-electrode detection device includes a reference electrode positioning clip and its positioning plate, a counter electrode positioning clip and its positioning plate, a working electrode and its lead-out rod. The working electrode has a round tube structure, and the reference electrode positioning clip positioning plate and the counter electrode positioning clip positioning plate are provided with an acid hole which communicates with the inner hole of the working electrode. The working electrode is clamped between the reference electrode positioning clip positioning plate and the counter electrode positioning clip positioning plate. The reference electrode positioning clip and the reference electrode positioning clip positioning plate are fixedly connected to the board surface on the side away from the working electrode, and the counter electrode positioning clip and the counter electrode positioning clip positioning plate are fixedly connected to the board surface on the side away from the working electrode. One end of the working electrode lead-out rod is connected to the working electrode, and the other end passes through the space between the reference electrode positioning clip positioning plate and the counter electrode positioning clip positioning plate and is exposed between the reference electrode positioning clip positioning plate and the counter electrode positioning clip positioning plate. outside the space. Beneficial effects: the processing and manufacturing are easy, the detection results are accurate and reliable, and the interference of the detection device on the results can be avoided.
Description
technical field [0001] The invention relates to the technical field of lead-acid batteries. Background technique [0002] Lead-acid batteries are safe to use, mature in manufacturing process, stable and reliable in performance, and relatively cheap in price, making them an important choice for power batteries and energy storage batteries. However, there are many problems in valve-regulated lead-acid batteries, such as early falling off of active materials and loss of initial capacity. These problems restrict the pace of development of lead-acid batteries. For these problems, many scientific researchers solve the problems by adding additives to the formula, preparing alloys with better corrosion resistance, and electrolyte additives. Application number 201510029145.9, authorized announcement number CN 104614678 B, titled "On-line detection device and method for battery electrode potential in the internal formation process of lead-acid battery" discloses a detection device an...
