1.4 Calendering

Updated 06/2025
Short Description
After drying, the coated electrode passes through the calendaring process, where it is compressed between precision rollers to achieve the desired thickness, density, and surface smoothness. This step is critical for tuning porosity, improving electrical conductivity, and ensuring mechanical adhesion between layers in the final cell.
Calendaring must balance compression with material integrity—too much pressure can cause cracking or delamination, while too little may result in low energy density and poor contact. The process is influenced by factors such as roller pressure, temperature, speed, and alignment. Uniformity across the width and along the length of the electrode is essential for consistent downstream performance.
