1. A method of fabricating an electrode, comprising:
calendering a briquette precursor so as to form a precursor sheet that includes components of an electrode active medium, the components including an active material;
cutting a briquette from the precursor sheet;
baking the briquette; and
performing multiple post-bake calender operations on the briquette after the baking of the briquette, each post-bake calender operation including calendering of the briquette, and
reducing a nip gap at which the post-bake calender operations are performed, the nip gap being reduced between at least a portion of the post-bake calendering operations, a total reduction of the nip gap between a first one of the post-bake calendering operations and a last one of the post-bake calendering operations is greater than or equal to zero and less than or equal to 0.02 inches.
