BATTERY PLATE NTRODUCE
The two electrodes of the chemical power source are composed of active materials and supporting and conductive "current collectors",
which are generally sheet-shaped porous bodies called polar plates.
Polar plates are often made by not adding active materials directly to the current collector, but raw materials are made into a paste and coated
on the grid, or the raw materials are poured into a glass filament tube, and then the activity is generated through the process of chemical
conversion. substance. The former is called pasted plate, and the latter is called tubular plate, which are two common plate forms in lead-acid
batteries. The raw materials can also be filled into the porous substrate, sintered and formed into a sintered plate (sintered plate), the nickel
electrode of the alkaline battery is made by this method.
Such as: negative plate (negative plate)
Pasted plate (grid type plate; pasted plate)
Sintered pole plate
The electrode plate is a network structure made of lead, and a chemically reactive active material is applied on it, such as a lead-acid battery.
Among them: the active material of the positive plate is lead dioxide powder, which looks a little brown after being fully charged.
The active material of the negative plate is spongy lead powder, which is gray of metallic lead after being fully charged, and 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
The acid radical loses electrons to produce electrons in the negative electrode. The electrons produce current in the outer circuit.
When charging: Contrary to the above process, lead sulfate is transformed into lead dioxide and pure lead with different energy states.
