Positive (+) Plate
A positively charged plate in a battery.
In lead-acid batteries, large-surface, grid or armored plates are often used for this purpose, whose surfaces are designed to carry as much lead dioxide (chemical formula PbO2) as possible.
In a rechargeable battery, the positive (+) plate is called the anode (strictly speaking, the designations anode and cathode depend on the chemical processes and thus the direction of current flow during charging and discharging, but this could lead to misunderstandings, so the designation is determined by the way the current flows during discharging).
