Abstract
Provided are methods of preparing a separator/anode assembly for use in an electric current producing cell, wherein the assembly comprises an anode current collector layer interposed between a first anode layer and a second anode layer and a porous separator layer on the side of the first anode layer opposite to the anode current collector layer, wherein the first anode layer is coated directly on the separator layer.
Claims21
A lithium battery comprising:
- an anode layer comprising a pigment dispersion, wherein said pigment dispersion comprises an organic solvent, an anode active material in pigment form, and a conductive carbon pigment;
- a porous separator layer, wherein said porous separator layer is selected so that there is no penetration of said conductive carbon pigment into said porous separator layer;
- and
- an anode current collector, wherein said anode layer is disposed between said porous separator layer and said anode current collector.
