摘要： There is provided a highly conductive and good silicon thin film which is obtained by applying a coating-type polysilane composition prepared by use of a polysilane having a large weight average molecular weight to a substrate, followed by baking. A polysilane having a weight average molecular weight of 5,000 to 8,000. The polysilane may be a polymer of cyclopentasilane. A silicon film obtained by applying a polysilane composition in which the polysilane is dissolved in a solvent to a substrate, and baking the substrate at 100° C. to 425° C. The cyclopentasilane may be polymerized in the presence of a palladium catalyst supported on a polymer. The palladium catalyst supported on a polymer may be a catalyst in which palladium as a catalyst component is immobilized on a functional polystyrene. The palladium may be a palladium compound or a palladium complex. The palladium-immobilized catalyst may be formed by microencapsulating a zero-valent palladium complex or a divalent palladium compound with a functional polystyrene. The zero-valent palladium complex may be a tetrakis(triphenylphosphine)palladium (0) complex.

摘要： A reactive separator is provided for a metal-ion battery. The reactive separator is made up of a reactive layer that is chemically reactive to alkali or alkaline earth metals, and has a first side and a second side. A first non-reactive layer, chemically non-reactive with alkali or alkaline earth metals, is adjacent to the reactive layer first side. A second non-reactive layer, also chemically non-reactive with alkali or alkaline earth metals, is adjacent to the reactive layer second side. More explicitly, the first and second non-reactive layers are defined as having less than 5 percent by weight (wt %) of materials able to participate in electrochemical reactions with alkali or alkaline earth metals. The reactive layer may be formed as a porous membrane embedded with reactive components, where the porous membrane is carbon or a porous polymer. Alternatively, the reactive layer is formed as a polymer gel embedded with reactive components.
