ABSTRACT:
Laminar electrical cells and batteries, each cell of which comprises a first electrode formed as a porous layer of electrochemically active particles on an electrically conductive, electrochemically inactive substrate coextensive with the particle layer. The electrochemically inactive substrate is adhered around its periphery to the borders of an aperture in an electrically insulating frame. A separator for each cell overlies the active particle layer of the first electrode and has borders extending beyond the borders of the first electrode and within the borders of the insulating frame. A second electrode for each cell comprises a slurry of electrochemically active particles in contact with the other side of the separator. Methods of making the above cells and batteries from elongated webs of electrically insulating ones of the constituent materials of the cells.
