An ${it in situ}$ experimental technique was developed for detecting structure changes at the electrode/electrolyte interface of lithium cell using synchrotron X-ray reflectometry and two-dimensional model electrodes with a restricted lattice plane. The electrode was constructed with an epitaxial film of LiNi$$_{0.8}$$Co$$_{0.2}$$O$$_{2}$$ synthesized by the pulsed laser deposition method. These films provided an ideal reaction field suitable for detecting structure changes at the electrode/electrolyte interface during the electrochemical reaction. The X-ray reflectometry indicated a formation of a thin-film layer at the LiNi$$_{0.8}$$Co$$_{0.2}$$O$$_{2}$$ (1 1 0)/electrolyte interface during the first charge-discharge cycle, while the LiNi$$_{0.8}$$Co$$_{0.2}$$O$$_{2}$$ (0 0 3) surface showed an increase in the surface roughness without forming the surface thin-film layer.
