Azobenzene-containing polymers exhibit light-responsive properties through reversible trans-cis isomerization. Here, we present a UV-triggered phase-transitionable azobenzene polymer that undergoes photoliquefaction, enabling a solvent-free and light-driven electrode fabrication process. Upon UV irradiation, the polymer melts and acts as a temporary medium for slurry-free electrode casting. Once the light is removed, it re-solidfies, functioning as a binder. This rreversible solid-liquid behavior allows uniform coating on the current collector without organic solvents or thermal curing. Electrodes fabricated via this method demonstrate stable adhesion and electrochemical performance comparable to those prepared by conventional slurry casting. our approach highlights a novel use of azobenzene polymers as functional materials that integrate photchemical responsiveness and binder capability, offering a sustainable route for next-generation lithium-ion battery electrode processing.
