Table 8.
Relative weight fraction of each phase within the recycled LLZO samples in respect to different excess amount of Li2CO3. The La2O3 and ZrO2 precursors were obtained from leaching a mixture of LFP/LLZO/LTO in HCl solution with pH=1.0 (according to Figure 3). The data is obtained from Rietveld refinement of the XRD patterns of the respective recycled LLZO samples.
