Abstract
A battery element useful as at least a portion of the positive plates of a lead-acid battery comprises an acid resistant substrate coated with electrically conductive doped tin oxide. This battery element may also be used in the bipolar plates of a lead-acid battery.
Claims5
A process for at least partially coating fibers with an electrically conductive, fluorine doped, tin-containing coating comprising (1) contacting a vaporous composition comprising at least one component of tin and at least one fluorine-containing component with said fibers;
- and (2) contacting said contacted fibers with an oxygen-containing vaporous medium at conditions effective to form said electrically conductive, fluorine doped, tin-containing coating on said fibers, provides that said fibers are maintained in substantially constant three dimensional motion during steps (1) and (2).
