Description

Depth profiles of Li transported in Au/LiCoO2 /LATP/Pt (LAPT= Li3.1Al0.83Ti1.17Ge1.27P1.73O12) specimen have been in-situ measured at several stages of charging by means of the elastic recoil detection (ERD) technique with 9 MeV O+4 ion beam . ERD data have shown that due to the first charging 1 μA for 10min the Li composition in LiCoO2 rapidly in time and steeply decreases to 0.8 at interface with Au and increases up to 1.1 with increasing depth from Au toward LAPT. With supplying charge, the slope in the Li composition from Au to LAPT increases gradually. This result has been concluded, however, to be due to radiation effects of probing 9MeV O ions, since on a non-irradiated part of the specimen Li is almost completely depleted from LiCoO2. New data on non-irradiated parts, measured always by shift of the specimen, have shown that Li is uniformly (flat) and continuously depleted from LiCoO2 with supplying charge. Radiation effects of the probing O ions on Li transport in the Li ion battery is discussed in comparison between the depth profiles on non-irradiated and irradiated parts. (author)
