Patent ID: 7078129

Claim:
An improved battery cell comprising: a cell can having a cell casing in sealed communication with a cell cap and having an interior cavity; means for insulation of said cell casing from direct contact with said cell cap; a first current collector in said interior cavity having a first planar surface and a second planar surface; said first planar surface in contact with said cell cap; a first electrode adhered to said second planar surface, said first electrode and said first current collector thereby forming a unitary structure; a porous second current collector in said interior cavity having an upper planar surface and a lower planar surface; said lower planar surface in contact with said cell casing; a second electrode adhered to said upper planar surface, said second current collector and said second electrode thereby forming a second unitary structure; said first current collector and said second current collector, both formed from one or a combination of materials from a group of materials consisting of particle-dispersed plastic tape, plastic dispersed carbon tape, fiber dispersed conductive plastic and carbon tape, particle and metallic powder dispersed conductive plastic; at least one of said first current collector and said second current collector being rendered fire retardant by addition of collector fire retardant material thereto; and a separator in contact with said upper planar surface and said second planar surface.
