Abstract
A polymer includes a first repeating unit having a cationic group and a second repeating unit having an anionic group. The polymer may further include a third repeating unit having a non-ionic group. The polymer may include first and second polymers, each of which includes a first repeating having a cationic group and a second repeating unit having an anionic group. The cationic group of the first polymer may form an intermolecular bond with the anionic group of the second polymer, and the anionic group of the first polymer may form an intermolecular bond with the cationic group of the second polymer. An electrode for a lithium secondary battery includes the polymer, and a lithium secondary battery employs the electrode.
