ELECTRODE BINDER COMPOSITE

摘要

An objective of the present invention is to provide an electrode binder composite whereby an accumulator device is given wherein charge-discharge capacitance is large, and deterioration in capacitance owing to repeated charge-discharge cycles is small. The present invention is an accumulator device electrode binder composite, including at least (A) polymer particles, (B) at least one type of polymer selected from a group comprising polyamic acid and a partially imidized polymer thereof, and (C) a liquid medium.
