"The copolymer of acrylamide and N,N ‘-methylene diacrylamide is the 3D framework of hydrogel electrolyte, and zinc salt is the zinc source... The battery showed high cycling stability of over 3,000 cycles, a high reversibility thanks to a Coulombic efficiency of up to 99.5%, and electrochemical performance of 185 mAh·g over 10,000 cycles... voltage of the zinc-ion battery device remained constant after it was bent at different angles"
