Abstract
The performance characteristics of alkaline manganese dioxide cells are improved by applying a thin, polymeric coating to the inner surface of an unplated steel positive current collector, and including a silicon compound in the coating. The polymeric coating comprises, in combination, a first film forming binder component and a second component comprising an electrically conductive component such as carbon or a filler. The combination of the coating and the silicon compound reduces the internal resistance of the cell, and may be used on unplated steel.
