Probing lithium diffusion in olivine materials LiMPO4 using muSR
We can trace the history of electrochemical cells just over two hundred years back to Luigi Galvani and Alessandro Volta¿s inventions, and perhaps more than a millennium further... -
Determination of diffusing species in LiFePO4 with negative muons
By means of a positive muon spin rotation and relaxation (mu+SR) technique, we have investigate Li and Na ion diffusion in many battery materials. Among them, it was found that... -
Carrier density in novel Li ionic conductors studied with muons
When we know an intrinsic diffusion coefficient of Li-ion (D) in an ionic conductor, we could estimate a number of mobile Li ions, i.e. carrier density (n), from ionic... -
Particle and temperature dependent solubility limits in LiFePO4
In extension of our previous study on particle size dependent solubility limits in nano-sized LiFePO4 we wish to extend our study to temperature dependent solubility limits in... -
Variable temperature studies and local structure analyses of LiFe1-xMnxPO4 na...
In order to probe Li content, cation distribution and defects in a series of LiFe1-xMnxPO4 nanoparticles, we propose the use of neutron powder diffraction and pair distribution... -
Li diffusion in complex olivine, Li(FeMn)PO4
This is a part of our Li-diffusion study in battery materials with muSR. In order for balancing safety and energy density, a solid solution system between LiFePO4 and LiMnPO4... -
Self-consistent Hubbard parameters from density-functional perturbation theor...
The self-consistent evaluation of Hubbard parameters using linear-response theory is crucial for quantitatively predictive calculations based on Hubbard-corrected...
