Surface| Zusammenfassung: | The changes of the electrical properties of lithium power sources with the cathode on the base of ceramic spinel LiMn1,9Fe0,1O4 have been researched. The original technique of shooting of the impedance spectra, which allows the establishment of the conducting properties of the cathode mixture on the amount of intercalated lithium have been used. It was concluded that the appearance of additional semicircles on the hodograph at large "guest" loads associated with the deposition of lithium on the surface and with the intercalates mesostructural entities that different by the interconnected electronic conductivity and varying degrees of lithiation. |
