Published: May 2, 2025

Stretchable electronics are transforming next-generation wearables and robotics, creating a significant demand for compatible energy storage devices. Microbatteries, known their compact flat design, hold great promise but often face limitations of low strain tolerance unidirectional stretchability. Here, we introduce omnidirectionally stretchable Zn-MnO2 microbatteries featuring innovative nanocomposite current collectors. These collectors comprise serpentine-patterned silver nanowire carbon nanotube nanocomposites embedded in soft elastomer, which effectively dissipate across all directions. The resulting microbattery achieves impressive performance, including high capacity (>1.5 mAh cm-2), excellent rate capability (up to 5.0 mA robust operation under omnidirectional/biaxial strains. Additionally, multiple cells successfully integrated with wireless charging circuit LED array, forming wearable system that seamlessly conforms body movements. This work establishes novel design framework deformable devices, merging superior electrochemical performance multidirectional

Abstract Zn‐ion microbatteries (MBs), distinguished by their simple fabrication process, low material costs, and high safety, are ideal candidates for powering microelectronic devices. Nevertheless, most MBs face momentous performance challenges of limited areal capacity insufficient cycling as a result poor contact between the electrode electrolyte. In this work, liquid–solid electrode–electrolyte is designed harnessing in situ generated iodine ionic liquids to produce Zn//I 2 solid with unprecedented energy storage capabilities, even at temperatures −20 °C. As result, demonstrate an ultrahigh 7.2 mAh cm −2 , density 8.3 mWh stable over 900 cycles Coulombic efficiency 99.8% room temperature. Even °C, still afford 3.9 4.1 . Operando spectroscopic analysis theoretical calculations employed track evolution liquid electrodes upon electrochemical cycling. Moreover, such integrated into flexible Bluetooth sensor modules, thereby ushering bright future microscale electronics.
