Within this work, the high capacitive lithium- and manganese-rich cathode active material LMR-NCM is for the first time employed in multilayer pouch cells (6-7 Ah) vs. graphite anodes and compared against established NCA/graphite cells. The LMR-NCM/graphite pouch cells reach ≈30% higher specific capacities and up to 11% higher energy densities on the cell level. Moreover, the investigation of effects related to gassing and a pronounced heat generation during cycling is only feasible in large-format cells, as these are not detectable in small-scale laboratory cells. These factors have to be considered for cells containing LMR-NCM during both the cell production and the later operation of the cell.
