The variation of the thin TiO2 electrode surface were tracked through the high-speed digital microscopy synchronized with the electrochemical measurement. Two characteristic interfacial behaviors were discovered: physical breakage of the titanium oxide and Li(l) spreading on electrode surface. These electrochemically induced interfacial behaviors affect the current-time curves due to the heterogeneity of the titanium oxide film shape.Springer2020-02engjournal articleAMhttp://hdl.handle.net/2115/80348https://doi.org/10.1007/s11663-019-01733-71073-5615Metallurgical and materials transactions B-process metallurgy and materials processing science5111115https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/80348/1/MMTB-marked_manuscript.pdfapplication/pdf755.49 KB2020-02
