Tags: What are battery plates and their characteristics? There are two types of battery plates, one is the positive plate and the other is the negative plate. For a battery to undergo a chemical reaction, the positive and negative plates must be grouped together to generate electricity. Then we understand the characteristics of the plate. The pole plate refers to the two electrodes of the chemical power supply composed of active materials and supporting and conductive 'current collectors'. They are generally sheet-like porous bodies. The active material called the positive plate of the pole plate is lead dioxide powder, which is fully charged. It looks a bit brown in the future. The active material of the negative plate is spongy lead powder, which is gray of metallic lead after being fully charged. The secondary plate is gray-white when the battery is discharged. During discharge: the lead dioxide on the positive plate is converted into lead sulfate, and the hydrogen ions in the acid are converted into water by electrons. The lead powder of the negative plate is also converted into lead sulfate, and the sulfate radical loses electrons to produce electrons in the negative electrode. Electrons generate electric current in the outer loop. When charging: Contrary to the above process, lead sulfate is converted into lead dioxide and pure lead with different energy states
