Abstract: A method of making a calendered electrode for a battery cell comprises introducing a coated electrode having a first surface extending thereover. The coated electrode has a predetermined density of active materials for ion transport. The method further comprises selectively modifying the coated electrode by patterning the first surface to define a patterned electrode having a first portion and a second portion. After the step of selectively modifying, the method further comprises compressing the patterned electrode by calendering the first surface to provide the first portion having a first density of active materials and the second portion having a second density of active materials. The second density is greater than the first density to define the calendered electrode having a spatial variation of active material density.
