The presence of lithium on the large interstitial site in lithium lanthanum titanate perovskites gives rise to exceptional ionic mobility. The lithium conductivity in this system can be as high as 10 S cm at room temperature, i.e. several orders of magnitude higher than many other fast lithium ion conductors. However, it must be noted that this is the value of conductivity within a crystallite and the presence of grain... [Pg.177]

The perovskite structure can be adjusted by the introduction of different cations to either dope the system, by using aliovalent cations, or simply by introducing cations of different sizes or polarisabilities in order to adjust the structure. In the lithium lanthanum titanate system a large number of cations can be introduced onto the A site in order to replace lanthanum or lithium l and this survey has found that the combination of lithium and lanthanum is exceptional. The similarities in the chemistry of the lanthanides are commonly exploited in structural chemistry by the substitution of one lanthanide cation with another of slightly different size. In the case of lithium lanthanum titanates this approach has a spectacular impact on the transport properties. [Pg.178]

The aims of the addition of inert ceramic filler to the electrospun polymer fiber matrix to form polymer/ceramic composite fiber membrane for separator in LIB were on one hand to prevent dimensional changes by thermal deformation at high temperature because of the frame structure of the heat-resistant ceramic powder and on the other hand to increase the ionic conductivity of the membrane due to the intrinsic ionic conductivity of the ceramics. Various ceramic fillers had been incorporated into the electrospun polymer membranes to make composite separators, including aluminum oxide (AI2O3) [61], fumed silica (SiOa) [29,48,62], titanium dioxide (Ti02) [50, 63-65], lithium lanthanum titanate oxide (LLTO) [51], and lithium aluminum titanium phosphate (LATP) [52],...
