An object of the present invention is to provide an excellent binder agent composition solving problems such as the decrease in a charge/discharge capacity that occurs in a case where a silicon-containing active material is used, a slurry composition and an electrode in which the binder agent composition is used, and a method for preparing the electrode. The present invention relates to 'a binder agent composition containing (A) one or more kinds of polymers containing polyacrylic acid, (B) a bivalent to decavalent alcohol, and (C) water', 'a slurry composition for lithium batteries, containing 1) a silicon-containing active material, 2) a conductive assistant, and 3) the binder agent composition', &#x201c;an electrode for lithium batteries that has 1) a silicon-containing active material, 2) a conductive assistant, 3) a binder agent derived from the binder agent composition, and 4) a current collector&#x201d;, and &#x201c;a method for preparing an electrode for lithium batteries, including coating a current collector with the slurry composition and drying the slurry composition after the coating&#x201d;.
