Light-driven dry process of lithium-ion battery electrodes utilizing solid–liquid phase transitioning polymers
We report a dry processing strategy for lithium-ion battery electrodes enabled by photoliquefiable azobenzene (Azo)-based polymers. In this approach, Azo polymers temporarily act as solvents, providing viscosity to the cathode composite by liquefying under UV irradiation. After UV removal, they spontaneously re-solidify at room temperature and serve as polymeric binders, enhancing the mechanical properties of electrodes. The resulting cathode delivers a specific capacity of ∼110 mAh g<sup>-1</sup> with 77% retention over 100 cycles.
