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 .
Challenges in Industrial Battery Cell Manufacturing The basis for reducing scrap and, thus, lowering costs is mastering the process of cell production. The process of electrode production, including mixing, coating and calendering, belongs to the discipline of process engineering.
The interaction of the organic electrolyte with the active material results in the formation of an SEI layer on the negative electrode surface . The composition and structure of the SEI layer on Si electrodes evolve into a more complex form with repeated cycling owing to inherent structural instability.
