What kind of structure of the battery?

The pole plate is divided into a positive plate and a negative plate, and each plate is composed of a grid frame and an active material. The active material on the positive plate is lead dioxide, which is brown-red; the active material on the negative plate is spongy pure lead, which is blue-grey. In order to increase the capacity of the battery, the positive and negative plates should be welded into a plate group, and the negative plate group has one more plate than the positive plate group. 2. Separator Separator is usually made of wood, microporous rubber, microporous plastic or glass fiber. The separator is installed between the positive and negative plates to prevent the positive and negative plates from colliding and short-circuiting. A groove is made on one side of the separator, and the grooved side should face the positive plate vertically during assembly. 3. Electrolyte The electrolyte is made up of pure sulfuric acid and distilled water in a certain proportion. The density can be measured with a densitometer, generally between 1.23 and 1.30g/cm3. 4. Shell The battery shell is made of rubber or plastic as a whole to store the electrolyte and support the electrode plate. There is a partition between two adjacent cells, and each shell is divided into three or six cells. 5. Each single-cell battery has a positive pole and a negative pole, which are connected to the positive and negative plate groups respectively. The one connected to the positive plate group is called the positive column, and the one connected to the negative plate group is called the negative column. The positive pole is connected to the starter switch pole, and the negative pole is connected to the frame (to the iron).
