Shape factor-free and shape-conformable power sources are highly desired for integration with complex-shape electronic devices. Herein, a new fabrication process for shape-conformable batteries is explored. Battery cells having targeted shapes are fabricated and assisted by 3D printing. Then, flowable semi-solid electrodes are used to fill in the prefabricated parts of the battery cell. The use of injectable hydrogel electrolytes enables semi-solid electrodes to possess special rheological properties as they are flowable during the fabrication process, while gelation of the electrolytes ensures their immobility during battery operation. Herein, poly(vinyl alcohol):gallic acid gels are investigated for aqueous Zn–LiFePO4 batteries. After evaluation of the effect of electrode formulation on the rheological properties as well as the ionic and electronic properties, simple-shape and UBU-shape batteries were fabricated using the best formulation. The prototype achieved areal capacities above 3 mA h cm−2, utilization rate between 150 and 180 mA h g−1 (LFP), and capacity fading of 0.2% h−1.
