From the perspective of manufacturing, direct ink writing (DIW)-based 3D printing has attracted unprecedented interest, paving the way to demonstrate micro-batteries with design freedom and outstanding performance. Despite demands for all-printed Li-ion batteries with maskless processing, most of the efforts have been dedicated to developing printable active electrodes or building the 3D architecture, remaining challenges in both manufacturing and printable materials toward form-free, all 3D DIW printed Li-ion batteries. Herein, we present all 3D DIW printed, scalable shape versatile Li-ion batteries (ADP-LIBs) with high-performance, printable gel polymer electrolytes (GPEs). The rheological optimization of DIW printable inks for solid-state current collectors, electrodes, electrolytes, and packaging enables us to demonstrate well-defined shape-versatile ADP-LIBs with reliable extrusion. In particular, UV-curable polydimethylsiloxane (PDMS) and ethoxylated trimethylolpropane triacrylate (ETPTA) monomers provide thixotropic fluid behaviors and a mechanical framework in the quasi-solid-state electrolytes, respectively, which results in high-throughput and mechanically robust printed electrolyte layers. Our ADP-LIBs demonstrate a great deal of promise as a realistic solution for powering the target applications on-demand with esthetic versatility, free-form factors, and competitive electrochemical performance.
