摘要： The unitary electrode (10) comprises a porous sheet of fiberglass resin phase (12) the strands (14) of which contain a coating (16) of conductive tin oxide. The lower portion of the sheet contains layer (18) of resin and the upper layer (20) contains lead dioxide forming a positive active electrode on an electrolyte-impervious layer. The strands (14) form a continuous conduction path through both layers (16, 18). Tin oxide is prevented from reduction by coating the surface of the plate facing the negative electrode with a conductive, impervious layer resistant to reduction such as a thin film (30) of lead or graphite filled resin adhered to the plate with a layer (31) of conductive adhesive. The plate (10) can be formed by casting a molten resin from kettle (60) onto a sheet of glass wool (56) overlying a sheet of lead foil and then applying positive active paste from hopper (64) into the upper layer (68). The plate can also be formed by passing an assembly of a sheet (80) of resin, a sheet (86) of sintered glass and a sheet (90) of lead between the nip (92) of heated rollers (93,95) and then filling lead oxide into the pores (116) of the upper layer (118).

摘要： A positive electrode 10 for a lead acid electric storage cell 24 is made by chemically preparing beta lead dioxide. The beta lead dioxide is then applied to a support structure 14 with a binder, or poured into a permeable, tubular container located about a current collecting rod. The negative electrode 26 can be made by compacting fine lead metal 30 about a carrier 32, and the fine lead metal might comprise lead wool or particulate lead metal.

摘要： The plate (10) comprises a matrix or binder resin phase (12) in which is dispersed particulate, conductive tin oxide such as tin oxide coated glass fibers (14). A monopolar plate (11) is prepared by coating a layer(18) of electrolytically active material onto a surface of the plate (10). Tin oxide is prevented from reduction by coating a surface of the plate (10) with a conductive, impervious layer resistant to reduction such as a thin film (22) of lead adhered to the plate with a layer (21) of conductive adhesive. The plate (10) can be formed by casting a molten dispersion from mixer (36) onto a sheet (30) of lead foil or by passing an assembly of a sheet (41) of resin, a sheet (43) of fiberglass and a sheet (45) of lead between the nip of heated rollers (48,50).
