Formation is one of the most important steps in battery cell production. This final step forms the Solid Electrolyte Interphase (SEI) on the negative active material and the Cathode Electrolyte Interphase (CEI) on the positive active material. These passivation layers are essential to suppress the continuous electrolyte degradation, thus enabling extended use of lithium-ion batteries […]
