Used as a monomer in the synthesis of lithium-functionalized polymers, particularly in developing ion-conductive materials for lithium-ion batteries. Its ability to coordinate with lithium ions makes it valuable in solid polymer electrolytes, where it enhances ionic conductivity and electrochemical stability. Also employed in stimuli-responsive hydrogels and smart materials due to its sensitivity to pH and ionic strength. Commonly copolymerized with other acrylic monomers to tailor mechanical and ion-transport properties in energy storage and sensor applications.
