Abstract
A method of preparing an electrochemical cell wherein the electrode material adheres to the current collector to create good electrical contact is provided. A critical aspect in the process of preparing the polymer mixture for both the anode and cathode slurries is that the polymer (or copolymer) not be subject to high shear so as to be degraded. Polymer degradation contributes to the creation of the polymer concentration gradient in the electrode film.
