Multicell electric storage batteries

摘要

A multicell electric storage battery of the type containing no mobile electrolyte includes a container 2 and a plurality of plates of which every alternate plate in the two end cells comprises a unipolar plate 6 and all the remaining plates constitute one half of a bipolar pair of plates 8 which is connected to its other half in an adjacent cell by one or more integral bridge pieces 10 whereby adjacent cells are separated and spaced apart only by the said bridge pieces. Each bipolar pair of plates 8 has a recess 14 engaging a corresponding projection 20 formed on one of two opposed side walls of the container thereby restraining movement of the bipolar pair of plates.
