A composition for forming a conductive film contains flat metal particles and a resin. The flat metal particles each have a metal oxide layer in the surface portion thereof. The flat metal particles have a ratio of the thickness of the metal oxide layer to the thickness of the flat metal particle of from 0.010 to 0.300. The thickness of the metal oxide layer is from 0.010 ?m to 2.000 ?m. In the method for manufacturing a conductive film, a composition for forming a conductive film is used, the composition containing flat metal particles and a resin. The composition for forming a conductive film is applied to a base material to form a coating film, and then the coating film is irradiated with light to sinter the coating film, thereby obtaining a conductive film.

An silicon-containing electrode is formed by coating a silicon-containing slurry onto a conductive current collector. The slurry comprises a binder solution comprising a poly(carboxylic acid) binder dissolved in a mixed solvent system comprising an amide solvent of Formula I, as described herein, and a second solvent which can be water and/or an organic solvent. The binder preferably comprises poly(acrylic acid). The mixed solvent system comprises about 10 to about 99 vol % of the amide solvent of Formula I. The binder solution is utilized as a solvent for a slurry of silicon-containing particles for preparing the silicon-containing electrode. The slurries comprising the mixed solvent system have higher viscosity and are more stable than slurries containing the same concentrations of silicon particles, carbon particles, and binder in water as the sole solvent.
