A lithium ion secondary battery has a high cycle retention rate, and has its battery capacity increased. A positive electrode active material is used which includes a crystal phase having a structure formed by collecting a plurality of crystallites 101, and powder particles containing amorphous phases 103a and 103b formed between the crystallites 101. The amorphous phases 103a and 103b contain one or more kinds of metal oxides selected from the group consisting of vanadium oxide, iron oxide, manganese oxide, nickel oxide and cobalt oxide. The crystal phase and the amorphous phase 103a and 103b are capable of intercalation and deintercalation of lithium ions.
摘要:
The conductive paste contains the following dispersed in a binder resin dissolved in a solvent: a plurality of particles comprising aluminum and/or an aluminum-containing alloy; and an oxide-comprising powder. The oxide contains vanadium with a valence no greater than 4 and a glass phase. In the method for manufacturing an electronic component, the conductive paste is applied to a substrate and fired, forming electrode wiring. The electronic component is provided with electrode wiring that has: a plurality of particles comprising aluminum and/or an aluminum-containing alloy; and an oxide affixing the particles to a substrate. The oxide contains vanadium with a valence no greater than 4. A compound layer containing vanadium and aluminum is formed on the surfaces of the particles, and the vanadium in the compound layer includes vanadium with a valence no greater than 4. This results in an electrode wiring with high reliability and water resistance.
