Binder jetting (BJ) has drawn attention to its ability to quickly produce complex objects using minimal amount of additives, being suitable for ceramic materials with high porosity. Thanks to these advantages, this additive manufacturing (AM) technique is now of interest in the field of energy storage.A successful NMC622 (LiNi0.6Mn0.2Co0.2O2) thick electrode was fabricated using an aqueous formulation showing a final porosity of 35%. When cycled in half cell configuration versus lithium metal between 4.3 and 3 V at 0.2 mA/cm2, the printed electrode delivers a reversible capacity of 155.2 mAh/g after 10 cycles. These results, presented as a proof of concept, establish Binder Jetting as a possible route to manufacture thick and self-supported electrodes with an areal capacity of 8.33 mAh/cm2 at 0.2 mA/cm2.
