Abstract
Wireless electronic devices require small, rechargeable batteries that can be rapidly designed and fabricated in customized form factors for shape conformable integration. Here, we demonstrate an integrated design and manufacturing method for aqueous zinc-ion batteries composed of polyaniline (PANI)-coated carbon fiber (PANI/CF) cathodes, laser micromachined zinc (Zn) anodes, and porous separators that are packaged within three-dimensional printed geometries, including rectangular, cylindrical, H-, and ring-shapes. The PANI/CF cathode possesses high surface area and conductivity giving rise to high rate (∼600 C) performance. Due to outstanding stability of Zn-PANI batteries against oxygen and moisture, they exhibit long cycling stability in an aqueous electrolyte solution. As exemplar, we demonstrated rechargeable battery packs with tunable voltage and capacity using stacked electrodes that are integrated with electronic components in customized wearable devices.
