Separation membrane coating agent composition, separation membrane made from coating agent composition, and battery using same
Disclosed herein is a coating composition having excellent thermal resistance and drying processability, utilizing polyamic acid having high thermal resistance and excellent solubility in a low boiling point solvent. Specifically, the coating composition includes polyamic acid and a low boiling point solvent having a boiling point less than 150° C. Also, disclosed herein a separator having improved thermal resistance by coating the coating composition on one or both surfaces of a polyolefin-based substrate film, and an electrochemical battery having improved thermal stability by using the separator.
