Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ТИТАНАТ ЛИТИЯ -- ФОСФАТЫ Аннотация: Li1 –xTi2 –xNbx(PO4)3 NASICON materials are prepared and studied by X-ray diffraction, 7Li and 31P NMR spectroscopy, and impedance spectroscopy. Vacancy mobility in Li1 –xTi2 –xNbx(PO4)3 is lower than interstitial lithium mobility. Nb5+cations with low doping levels increase cation mobility in LiTi2PO4)3 Полный текст |
