Electrode Calendering Optimization
Graphite electrodes were calendered at different temperatures (room temperature to 120 oC) with different nip openings (40 to 100 μm). Electrode density is correlated with electrochemical performance using data from coin cell hardware. Results show that the highest amount of calendaring does not necessarily result in the largest volumetric energy density. This may be due to excessive porosity reduction, which prevents the electrolyte from wetting all of the electrode particles.
