ELECTRODE FOR NONAQUEOUS SECONDARY BATTERY, NONAQUEOUS SECONDARY BATTERY USING THE SAME, AND METHOD FOR PRODUCING ELECTRODE

摘要

The non aqueous secondary battery electrode of the present invention includes a mixture layer and a porous layer formed on the surface of the mixture layer. The mixture layer includes an electrode material expressed by the composition formula SiOx where x in the composition formula satisfies 0.5≦̸x≦̸1.5, a conductive material and at least one binder selected from the group consisting of polyimide, polyamideimide and polyamide. The porous layer includes an insulating material unreactive with Li.
