Abstract
Abstract A system for the formation of the electrodes of an electrolytic cell, such as a lead acid cell, is built of cabinets housing panels, each of which supports an array of the cells. The cells are connected to a source of electric power for charging and discharging the cells during the formation operation. The connection of the cells to the power source is accomplished by strip conductors located behind apertures in the panels wherein the cells are placed and through which access to the conductors is provided for the cell terminals. Edges of the conductors are offset relative to the apertures, corresponding to an asymmetry in the location of the terminals of a cell, to provide a keying of the connection. The cells are securely grasped by friction forces exerted on the terminals by resilient edges of the conductors.
