Abstract
It is an object of the present invention to provide an electrode having superior charge-discharge capacity, even in the case of using an active material containing silicon. The present invention relates to 'a binder for a lithium cell comprises a polymer having a monomer unit derived from acrylic acid, and 1 to 2 kinds of monomer units derived from the compound shown by the general formula (I), the general formula (II), or the general formula (III), as constituents, and cross-linked by a cross-linking agent selected from the compounds described by the following general formulae [1] to [13], and the polymer described by the following general formula [14]', 'a composition for producing an electrode of a lithium cell comprising 1) an active material containing silicon, 2) a conductive assistant, and 3) the above-described binder for a cell', and “an electrode for a lithium cell having 1) an active material containing silicon, 2) a conductive assistant, 3) the above-described binder for a cell, and (4) a current collector”.
