1. An electrode comprising:
an electrochemically active material and a binder, the electrochemically active material intermixed with the binder; and
the electrochemically active material coated onto a current collector substrate;
wherein the electrochemically active material is an anode active material coated at an areal density of 10 mg/cm2 or greater and the binder distributed within the electrochemically active material such that the concentration ratio of binder at a surface of the anode active material relative to the binder at a current collector substrate surface is 3.0 or lower.
