This invention addresses the problem of providing an electrode with which excellent charge/discharge capacity can be obtained even when an active material containing silicon is used. The present invention pertains to: a binder for a lithium cell comprising a polymer that has, as constituent elements, an acrylic acid-derived monomer unit and one or two monomer units derived from compounds represented by general formulae (I), (II), or (III), the binder being crosslinked by a crosslinking agent selected from compounds indicated in general formulae [1]-[13] and the monomer indicated in general formula [14]; a composition for producing an electrode of a lithium cell, the composition containing 1) a silicon-containing active material, 2) an electroconductive aid, and 3) the binder for a cell; and an electrode for a lithium cell having 1) a silicon-containing active material, 2) a conductive aid, 3) the binder for a cell, and 4) a collector. |
