The purpose of the invention is to provide: an excellent binder agent composition that overcomes such problems as a reduction in charge/discharge capacity in cases of using a silicon-containing activematerial; a slurry composition and an electrode using said binder agent composition; and a method for preparing said electrode. This invention relates to: a binder agent composition comprising (A) atleast one type of polymer including a polyacrylic acid, (B) a bivalent to decavalent alcohol, and (C) water; a slurry composition for lithium batteries, comprising (1) a silicon-containing active material, (2) an electroconductive aid, and (3) said binder agent composition; an electrode for lithium batteries, comprising (1) a silicon-containing active material, (2) an electroconductive aid, (3) abinder agent derived from said binder agent composition, and (4) a charge collector; and a method for preparing an electrode for lithium batteries, characterized by applying said slurry composition on a charge collector, and then drying the same.
