**4. Conclusions**

Thanks to a multilayer approach, the gravure printing technique led to the production of functional composite layers. The feasibility to gravure print cathodes for batteries has been demonstrated and, even with only a few overlapped layers, good performances was achieved. Keeping most of the printing parameters constant during the production process and skipping the calendering step allowed the manufacturing process to be simplified, which would make its industrial scaling easier. The performances of the printed cathodes could be improved by increasing the layer homogeneity by decreasing the size and the size distribution of the starting materials. These results open the way to the possibility of utilizing such techniques in future industrial production, especially in the field of printed batteries.
