1. A method of manufacturing an electrode for an electrochemical cell, the method comprising:
providing an admixture including an electroactive material, a binder, and a solvent;
rolling the admixture to form a sheet;
forming a multi-layer stack from the sheet;
forming an electrode film precursor by performing a plurality of sequential rollings, each rolling including rolling the multi-layer stack through a first gap defined in a direction transverse to a plane of the multi-layer stack, the plurality of sequential rollings including,
a first rolling in which the multi-layer stack is in a first orientation with respect to a machine direction, and
a second rolling in which the multi-layer stack is in a second orientation with respect to the machine direction, the second orientation being different from the first orientation;
forming an electrode film by rolling the electrode film precursor through a second gap defined in the direction, the second gap being less than or equal to the first gap; and
drying the electrode film to remove at least a portion of the solvent to form the electrode.
