To further deconvolute the effects of microstructure, conductive additive and active material on the cyclic performance of these intercalation-type fluoride ion cathode composites, it was chosen to operate them with 180 MPa stack pressure at a rate of C/16 between 0-2 V against Pb/PbF2. The cycling data of these cells is shown in Figure and 7. Unfortunately, it was not possible to remove the gold current collector from the cathode surface of these cells, which makes recording an XRD of the cycled cathodes infeasible due to the very strong scattering and absorbance of gold. As it can be seen, both La2NiO4 and La2CoO4 were able to cycle with high coulombic efficiency at the theoretical capacity of 133.4 mAh g -1 after some initial activation cycles, far surpassing the discharge capacity and cyclic stability which has been reported before for these materials . This stable discharge capacity was independent of the conductive additive used. This revelation highlights again the importance of stack pressure for solid-state-batteries, while it also shows that intercalation cathodes for fluoride-ion batteries can operate at high potential, high capacity and high coulombic efficiency even if conductive carbon additives are used. This is in stark contrast to previous assumptions. Further, this indicates that the difference in cyclic stability without stack pressure as displayed in Figure might also stem from the different microstructure of the composites and their response to volume change upon cycling, as compared to chemical stability of the additives.
