Resumo(s)
Boron doped LiZr2(PO4)3 electrolyte was successfully synthesized via facile hydrothermal synthesis. Our results show that boron doping mainly happens on the Zr-site of Li1+xZr2-xBx(PO4)3 not the P-site of Li1+6xZr2(P1-xBxO4)3. Rietveld refinement of the unit-cell parameters was performed, and it was verified by consideration of Vegard’s law that it is possible to obtain phase purity up to x= 0.05 in Li1+xZr2-xBx(PO4)3. This corresponds with phases present in the XRD data, which shows the additional presence of the low temperature (monoclinic) phase for the powder sintered at 1200ºC for 12h of compositions with x ≥ 0.075. The compositions inside the solid solution undergo the phase transition from triclinic to rhombohedral when heating from 25 to 100ºC.
