Lithium tracer diffusion coefficients have been measured in Li

Ti
(PO
)
(LATP) and LATP - LaPO composite solid electrolytes in the temperature range between 300
C and 500C by means of neutron radiography technique that utilizes the difference in neutron attenuation of 
Li and 
Li isotopes. The diffusion coefficient of LATP - LaPO composite is higher than that of pristine LATP, although the difference is much smaller than that estimated from the room temperature conductivity. This suggests that the bulk diffusion becomes the predominant diffusion mechanism at 300C to 500C instead of the diffusion along the space charge layer formed around the LaPO dispersants.
