摘要:
A negative electrode for a rechargeable lithium battery which is obtained by sintering under a non-oxidizing atmosphere, in the form of a layer on a surface of a metal foil current collector, an anode mix containing a binder and particles of active material containing silicon and/or a silicon alloy; the negative electrode being characterized in that the metal foil current corrector has projections and recesses on its surface, the projection is shaped to have a recurved side face portion that curves more outwardly as it extends closer to a distal end of the projection, and the binder penetrates into spaces defined by the recurved side face portions.
摘要:
An electrode for a rechargeable lithium battery characterized in that thin films of active material capable of lithium storage and release, i.e., microcrystalline or amorphous silicone thin films are deposited on opposite faces of a plate-form current collector.
摘要:
A method for preparing an electrode material for a lithium battery, characterized in that a noncrystalline silicon thin film that serves as an active material is deposited on a substrate.
摘要:
A method of manufacturing an electrode for a secondary battery by depositing a thin film composed of active material on a current collector in which a surface-treated layer such as an antirust-treated layer is formed, including the steps of: removing at least part of the surface-treated layer by etching the surface of the current collector with an ion beam or plasma in order to improve the diffusion of the current collector material into the active material thin film; and depositing the thin film on the surface of the current collector subjected to the etching step.
摘要:
A method for fabricating an electrode for a rechargeable lithium battery which includes depositing a thin film composed of active material capable of alloy formation with lithium on a current collector made of a metal incapable of alloy formation with lithium, by using a process for depositing a thin film by supplying a material from a gas phase, characterized in that the thin film of active material is deposited at such a temperature that enables formation of a mixed layer via diffusion of a constituent of the current collector into the thin film in the vicinity of an interface therebetween.
摘要:
A thin film magnetic head includes a magnetoresistive element portion movable over and relative to a magnetic recording medium for reading information stored therein, upper and lower shielding layers disposed with the magnetoresistive element portion therebetween for magnetically shielding the magnetoresistive element portion, and upper and lower gap insulative layers respectively interposed between the upper shielding layer and the magnetoresistive element portion and between the lower shielding layer and the magnetoresistive element portion. Each of the upper and lower gap insulative layers includes a hydrogen-incorporated film. The upper gap insulative layer has an increased hydrogen content and a reduced internal stress relative to the lower gap insulative layer.
