Nickel-Cadmium Pocket Plate Battery Design Question

May 21, 2013

Q. Hi. This is my 1st post here.
In Ni-Cd battery, the mixture of Nickel oxide is loaded in a porous casement of Nickel plated steel (Pocket Plate). This casement is connected to the main terminal of the battery. If we charge the battery, does the nickel plated casement (Pocket Plate) take part into the conduction of current even if active material (Nickel Oxide) is not present in the porous pockets? I mean, the Nickel plated porous steel casement will cause a short circuit or not?
Please answer this question. Thanks.
