A class of imprintable, bendable, and shape‐conformable polymer electrolyte with excellent electrochemical performance in a lithium battery system is reported. The material consists of a UV‐cured polymer matrix, high‐boiling point liquid electrolyte, and Al2O3 nanoparticles, formulated for use in lithium‐ion batteries with 3D‐structured electrodes or flexible characteristics. The unique structural design and well‐tuned rheological characteristics of the UV‐curable electrolyte mixture, in combination with direct UV‐assisted nanoimprint lithography, allow the successful fabrication of polymer electrolytes in geometries not accessible with conventional materials.
