Laminar batteries and methods of making the same

A laminar electrical cell, comprising a first electrode formed as a porous layer of electrochemically active particles on an electrochemically inactive substrate coextensive with the particle layer, a frame of insulating material formed with a central aperture, said electrochemically inactive substrate being adhered to said frame around its periphery to the borders of said aperture, a separator overlying the active particle layer of said first electrode and having borders extending beyond the borders of said first electrode and within the borders of said frame, discontinuous strips of adhesive between said separator and confronting portions of said frame, a second electrode comprising a slurry of electrochemically active particles in contact with said separator on the side of said separator opposite said first electrode;

• and a metal terminal collector sheet adhered to said frame on the side of said frame opposite said first electrode and adhered to said electrochemically inactive substrate in regions within the boundaries of said aperture.

A laminar electrical battery each cell of which comprises a first electrode formed as a porous layer of electrochemically active particles on an electrochemically inactive substrate coextensive with the particle layer, a frame of insulating material formed with a central aperture, said electrochemically inactive substrate being adhered to said frame around its periphery to the borders of said aperture, a separator overlying the active particle layer of said first electrode and having borders extending beyond the borders of said first electrode and within the borders of said frame, discontinuous strips of adhesive between said separator and confronting portions of said frame, a second electrode comprising a slurry of electrochemically active particles in contact with said separator on the side of said separator opposite said first electrode, and a metal terminal collector sheet adhered to an external one of said frames on the side of said frame opposite said first electrode and adhered to said electrochemically inactive substrate in regions within the boundaries of said aperture.
