Abstract: The present invention relates to a binder composition for lithium-ion secondary battery electrodes. Recently, there is a need for a lithium-ion secondary battery which has the excellent property of accommodating an abnormal situation so that in cases when the battery has heated up abnormally or is in an abnormally high-temperature environment, the battery can lower the charge/discharge performance thereof. The present invention solves the above-mentioned problem by using, as a binder for electrodes, composite polymer particles obtained by polymerizing, in an aqueous medium, a monomer solution containing a polymer.
