G. Papazov, in Encyclopedia of Electrochemical Power Sources, 2009 The negative plate consists of negative lead grid and negative active mass (NAM). The lead grid supports the negative active material and it is a current conductor for the electricity generated in the negative active material, as well as a conductor for the charge current.
In Electrical Systems and Equipment (Third Edition), 1992 The negative plate in a lead acid cell consists of a lead alloy lattice or grid in which the spaces of the grid are filled with chemically-active lead sponge.
The plates are connected at the top by a cast-on strap that is welded to the plates. The elements fit into the individual cells of each battery. Battery Paste: The paste is a lead oxide mixture that creates both lead dioxide and sponge lead. It adheres to the positive and negative battery grids.
Battery Separator: The separator is a polyethylene material that separates the positive plates from the negative plates to provide an efficient flow of electrical current. Positive Battery Plate: The positive plate contains a metal grid with lead dioxide active material.
Battery Plates: The element consists of stacked alternating positive and negative plates. The plates are connected at the top by a cast-on strap that is welded to the plates. The elements fit into the individual cells of each battery. Battery Paste: The paste is a lead oxide mixture that creates both lead dioxide and sponge lead.
Battery Negative Plate: The negative plate contains a metal grid with spongy lead active material. Battery Separator: The separator is a polyethylene material that separates the positive plates from the negative plates to provide an efficient flow of electrical current.
