*2.1. Binder Polymer Variation*

For the binder polymer (BP) variation, different BPs based on aqueous solutions or dispersions, as well as non-aqueous solutions, were investigated. Since an aqueous electrolyte is used in the cell, the mechanical stability and structural integrity, especially of those electrodes produced with an aqueous binder preparation, were of interest.

In the following, the BPs based on aqueous solvent preparations are summarized as *aqueous electrodes*, whereas the BPs based on non-aqueous solvent preparations are summarized as *non-aqueous electrodes*.
