TL;DR: An electrode for lithium secondary battery having a current collector and, deposited thereon, a thin film comprising silicon as a main component, characterized in that the thin film containing silicon contains at least one of the elements belonging to the groups IIIa, Iva, Va, VIa, VIIa, VIII, Ib and IIb in the fourth, fifth and sixth periods of the Periodic Table as discussed by the authors.

TL;DR: An electrode for a lithium cell having an active material thin film absorbing/desorbing lithium such as a microcrystalline silicon thin film or an amorphous silicon thin films provided on a current collector, characterized in that a component of the current collector is diffused into the thin film as discussed by the authors.

TL;DR: In this paper, an amorphous material such as polysilicon containing at least one kind of impurities selected from carbon, oxygen, nitrogen, argon, and fluorine is used as the active material.

TL;DR: An electrode for a lithium battery having a thin active material composed of active material capable of lithium storage and release, provided on a current collector, the electrode being characterized in that the current collector has a surface roughness of 0.01 μm or greater.

TL;DR: In this article, an electrode for lithium secondary battery, formed by accumulating the thin film formed of the active material storing and releasing lithium on the current collector, an intermediate layer containing Mo or W is formed on the collector, and the active materials thin film is accumulated on the intermediate layer.
