Status of active material shedding on lead plates for anatomical examination of lead batteries
Active materials for battery plates are lead dioxide and porous metal lead. In the long-term function, the battery is continuously charged and discharged. The active material of the electrode plate undergoes a redox reaction, the volume changes, the expansion and contraction repeat, and the active material gradually becomes soft and detached, especially the positive electrode plate is more obvious and should be regarded as normal. In some batteries, a large amount of active materials fall off at an early stage, which is an abnormal phenomenon. Its characteristics are: capacity reduction, temperature increase, electrolyte turbidity, and large gas evolution.
The current status of active substance shedding on anatomy check plates is:
1. A large amount of deposits are deposited on the bottom of the battery, and the electrode plate shows exposed grid ribs. There are a lot of lead floc on both sides of the electrode group, and the electrolyte is turbid and iron-cyan.
2. The color of the precipitate is gray-brown, indicating that there are more iron and copper impurities; the precipitate is light blue or off-white, indicating that the density of the electrolyte in the battery is high.
3. Precipitation is a paste, which means that the temperature of the battery is too high; if it is a block, it means that there is a priority in manufacturing.
