Abstract
A battery element useful as at least a portion of the positive plates in a lead-acid battery comprises: an acid resistant substrate at least partially coated with an electrically conductive coating; and a fluid impervious matrix layer having mutually opposing first and second surfaces situated such that at least a portion of the coated substrate is embedded in the matrix layer which comprises polymer having increased polarity relative to polypropylene. This battery element may also be used in the bipolar plates of a lead-acid battery.
