| Outline of Final Research Achievements |
The content and dynamics of Li ions at the interface between an electrode and electrolyte in a multi-layer film sample was studied with a positive muon spin rotation and relaxation (μ+SR) technique. A space charge layer (SCL), where the Li content is seriously reduced, was not detected, meaning that the thickness of SCL ranges below 10 nm, based on the depth profile of the positive muon beam.
Concerning the diffusing species for the μ+SR experiment, it is confirmed that Li is diffusing in an olivine-type and a spinel-type cathode materials by μSR with negative muons.
