抄録: | The migrations of lithium (Li) as well as hydrogen (H) in multi-layers thin films of Au/LiCoO2 (thickness: approximately 42 nm/80 nm), deposited onto one face of Li1.4Ti2Si0.4P2.6O12-AlPO4 (LATP) substrates, were dynamically observed with electric charging as well as isochronal annealing in vacuum by combining elastic recoil detection (ERD) analysis with Rutherford backscattering spectrometry (RBS)with 9.0-MeV O4+ ion-probe beams. The ERD spectra clearly revealed that Li atoms of approximately 9.4 at% migrated from the LiCoO2 surface to the LiCoO2/LATP interface with H absorption by a charge of approximately 0.48 e/cm2, which the acquiredvoltage was1.65 V. In addition, the diffusion of Li atoms to the LATP bulk occurred with H release by isochronal annealing at only 323 K for 10 min.The presence of H significantly influences the Li+ ion conduction for the Li-battery systems. |
