Electrochemical properties and structure changes of nano-sized Li$$_{4}$$Ti$$_{5}$$O$$_{12}$$ during lithium (de)intercalation wereinvestigated using a two-dimensional thin film electrode. Li$$_{4}$$Ti$$_{5}$$O$$_{12}$$ thin films were deposited on a Nb:SrTiO$$_{3}$$(110)substrate by a pulsed laser deposition technique. In situ X-ray diffraction measurements clarified the drastic structural changes of the Li$$_{4}$$Ti$$_{5}$$O$$_{12}$$film upon soaking in the electrolyte and during the first intercalation and deintercalation processes. The surfaceregion of Li$$_{4}$$Ti$$_{5}$$O$$_{12}$$ had a different structure from the bulk during electrochemical cycling and could cause the nanosizedLi$$_{4}$$Ti$$_{5}$$O$$_{12}$$ electrodes to have high capacities and poor stabilities.
