<p>A binder for cells containing particles of composite polymer such that two or more polymers having different chemical structures form a heterogeneous phase structure. Preferably the polymers include polymers having glass transition temperatures (Tg) different from each other by 5 °C or more. When slurry prepared by mixing the binder with a liquid material and an active material is used for the manufacture of the electrode of a secondary cell, especially, a lithium secondary cell, the performance of the cell is improved because the slurry imparts a well-balanced binding power and a binding persistence.</p> |
