One of the most challenging issues for the development of independent stretchable electronics is the fabrication of the stretchable energy storage devices. Lithium-ion batteries (LIBs) have been frequently used to power electronic devices owing to their many advantages. Aqueous rechargeable Li-ion batteries (ARLBs) based on water-based electrolytes are intrinsically safer and have high energy/power. In this work, we report on a bio-inspired Jabuticaba-like hybrid carbon/polymer (HCP) composite that was developed into a stretchable current collector using a simple and cost-effective solution process. In order to understand the percolation behavior of the conductive fillers in the polymer, we used the in situ small-angle X-ray scattering (SAXS) analysis. Using the polymer composite as a stretchable current collector, we have, for the first time, developed stretchable ARLBs as a stretchable power source, and they delivered excellent rate capability and outstanding durability |
