Fiber reinforced grid for a storage cell, and method of manufacturing it

摘要

A grid (10) for the plate of an electrical storage cell, eg. a lead-acid accumulator, comprises two orthogonal sets of conductive bars (7, 8) together with a current collector tab (9). The grid is made from a loosely-woven cloth comprising both bundles of conductive threads outlining the bars and the current collector of the plate, and bundles of non-conductive threads (6) serving to position said conductive threads relative to one another and to maintain them in position. Said bundles of conductive threads are embedded in a metal matrix comprising at least one of the metals in the group constituted by: lead, copper, cadmium, and nickel.
