The present invention relates to a plate ( 20 ), particularly for a bipolar battery ( 10 ), the plate ( 20 ) being of the type that comprises a base graphite material ( 2 ), a positive active material ( 3 ) applied to a first surface ( 4 ) of the base material ( 2 ) and a negative active material ( 5 ) applied to a second surface ( 6 ) of the base material ( 2 ) opposite the first surface ( 4 ), the positive active material ( 3 ) having a composition that comprises lead dioxide, conductive carbon fibers and glass microspheres, and the negative active material ( 5 ) having a composition that comprises spongy lead, graphite additives and glass microspheres. One further describes a bipolar battery ( 10 ) formed by a plurality of plates ( 20 ), each plate ( 20 ) comprising a graphite base material ( 2 ), positive active material ( 3 ) applied to the first surface ( 4 ) of the base material ( 2 ) and negative active material ( 5 ) applied to a second surface ( 6 ) of the base material ( 2 ), opposite the first surface ( 4 ), the positive active material ( 3 ) of the plurality of plates ( 20 ) having a composition that comprises lead dioxide, conductive carbon fibers and glass microspheres, and the negative active material ( 5 ) of the plurality of plates ( 20 ) having a composition that comprises spongy lead, graphite additives and glass microspheres. |
