摘要：

Li-V2O5 reserve cells which differed only in the bulk lot from which the vanadium pentoxide cathode material was derived showed very significant difference with regard to sustained performance. The V2O5 which constituted the batteries displaying premature breakdown and irregular behavior in voltage output versus time was characterized by: (1) less euhedral and smaller microcrystallites, (2) lower electrical resistivity, (3) a shift in peaked visible reflectance of about 200Å, and (4) a slghtly greater oxygen content from ESCA measurements on the 1s state electrons, as compared to V2O5 from lots which constituted satisfactorily performing batteries. © 1979.
