Lithium Composite Oxides,Elastic Recoil Detection

The elastic recoil detection (ERD) spectra revealed that the Li concentration in Li₄SiO₄ hardly changed with increasing the annealing temperature in vacuum, while the H one exponentially decreased. This indicated that the improvement of the Li conduction characteristics might be expected by the desorption of H preventing the Li migration.
