After accessing the comma gap's influence on the mesostructured electrode, we characterize the electrodes using two different Si contents when coated using a comma gap of 200 µm. The comma gap chosen is suited for prototype electrochemical applications, and the electrode thickness allows us to investigate the calendaring effect on the electrochemical performance. The electrodes were calendered at 10%, 20%, and 30% of their initial thickness. Additional information on the calendered procedure is presented in Methods.
