Abstract
The electrical conductivity of samples having Li4Si04 and Li3VO, in
solid solution bas been studied as a function of both temperature (in the
range 30°-300°C} and composition by the a~ technique. The highest
conductivity (~ to-s obm-cm-1 at 200°C} was found at 40 mol%
Li3V04• The activation energy was around 0.45 eV. The conductivity
value was comparable to that of Li3•6Si0•6P0• 40 4 and Li,.Zn(GeO,).,
the two most conducting lithium solid electrolytes reported so far.
DC polarization study indicated that the transport number of lithium
ion was more than 0.95 and the electronic conductivity was at least
5 orders of magnitude lower than that due to ionic migration.
