In order to improve the performance of future energy devices, nano-structuring materials is one of the most promising routes. LiFePO4 is a commercial battery cathode material where nanostructuring is of specific interest due to its anisotropic crystal structure where the Li ion diffusion occurs in 1D channels. In this continuation of an earlier Muon experiment we propose to further study the microscopic Li ion diffusion in nano-structured LiFePO4 samples. With our synthesis protocol we are able to produce high-quality nano-platelets with different coatings and channel lengths below 15nm. This will allow us to obtain samples and study their Li ion diffusion with respect to the surface coating and the strain they form. The results will be correlated with our parallel studies of the surface phonon spectrum in the same samples acquired by inelastic neutron scattering.
