Nanoscale kinetic imaging of lithium ion secondary battery materials using scanning electrochemical cell microscopy

To visualize the electrochemical reactivity and obtain the diffusion coefficient of the anode of lithium-ion batteries, we used scanning electrochemical cell microscopy (SECCM) in a glovebox. SECCM provided the facet-dependent diffusion coefficient on a Li 4 Ti 5 O 12 (LTO) thin-film electrode and d...

Summary:To visualize the electrochemical reactivity and obtain the diffusion coefficient of the anode of lithium-ion batteries, we used scanning electrochemical cell microscopy (SECCM) in a glovebox. SECCM provided the facet-dependent diffusion coefficient on a Li 4 Ti 5 O 12 (LTO) thin-film electrode and detected the metastable crystal phase of Li x FePO 4 . To visualize the electrochemical reactivity and obtain the diffusion coefficient of the anode of lithium-ion batteries, we developed scanning electrochemical cell microscopy (SECCM) in a glovebox.
