A new kind of all-solid-state thin-film-type lithium-ion battery was fabricated by applying a D.C. high voltage. Application of the D.C. high voltage to a layer of Cu/Li2O-Al2O3-TiO2-P2O5-based glass ceramics sheet/amorphous Li-Mn-O/Pt, where Cu side was connected to cathode and Pt side to anode, permitted an in situ formed negative electrode material at the Cu/glass ceramics sheet interface. This negative electrode material was reductive decomposition material of the glass ceramics formed at the glass ceramics/Cu interface. The negative electrode material was irreversibly formed and then some of reaction current was required to be prepared. It was suggested that application of D.C. high voltage to the layer induced the oxidation reaction of oxygen ions at the positive electrode side around the amorphous Li-Mn-O/glass ceramics interface, which was consumed to prepare the negative electrode material. The resultant all-solid-state thin-film-type lithium-ion battery repeated stable charge-discharge reaction at 1.4 V. (c) 2006 Elsevier B.V. All rights reserved.
