An electrode consists of an electroactive material, as well as a binder material, which enables structural integrity while improving the interconnectivity within the electrode, adhesion to the current collector and the formation of the solid electrolyte interface (SEI) during the first battery cell cycles .
Electrode manufacture involves several steps including the mixing of the different components, casting in a current collector and solvent evaporation . After the solvent evaporation step, a calendering process is used to reduce porosity and to improve particles cohesion, consequently improving battery performance .
Electrode final properties depend on processing steps including mixing, casting, spreading, and solvent evaporation conditions. The effect of these steps on the final properties of battery electrodes are presented. Recent developments in electrode preparation are summarized.
