Gel polymer electrolyte self-polymerized at room temperature, method for manufacturing same, and secondary battery containing same

The present invention relates to a gel polymer electrolyte self-polymerized at room temperature, a method for manufacturing the same, and a secondary battery comprising the same. The gel polymer electrolyte is a gel polymer electrolyte that is self-polymerized and then self-crosslinked without initiators, crosslinkers, and external energy, and is capable of suppressing dendrite formation with high mechanical properties by controlling the concentration of the self-polymerized polymer. When applied as an aqueous zinc battery gel electrolyte, it induces high stability and electrochemical characteristics, and significantly improves the lifespan of the battery by eliminating interfering residues inside the battery system and compounds causing chemical side reactions, thereby improving the capacity characteristics of the battery.
