What is the role of plates inside a battery?
The plate grids are the vital elements of the battery. There are two types of plates — positive plates and negative plates. The positive plates consist of a grid over which active lead peroxide is placed. This dark brown crystalline material has a high degree of porosity in order to allow the electrolyte to penetrate the plate freely. Negative plates are grids pasted with a type of lead referred to as sponge lead, which is simply finely ground lead. Grinding the lead allows the electrolyte to penetrate the grid. There may be any number of plates used in a battery; it all depends on how much energy you want to store. The more plates (or the larger the plates), the more energy the battery can store and release. The negative plates will always outnumber the positive plates by one for reasons of improved performance.
