摘要

The rapid expansion of the Internet of Things (IoT) has fueled the demand for high-energy, compact microbatteries capable of powering energy-demanding IoT devices in small, flexible formats. Li–S batteries offer a promising solution but suffer from more intense polysulfide (LiPS) shuttling in the limited volume of microbatteries. Here, we achieved a high-energy quasi-solid-state Li–S microbattery by employing 3D-printed hierarchically structured sulfurized polyacrylonitrile (3D-HSPAN) cathodes with plasmonic enhancement. The direct ink writing technique produces shape-customizable 3D-HSPAN cathodes with precise architectural engineering, ultra-high mass loading up to 37.1 mg cm−2, and greatly improved ionic transport. Plasmonic MXene is harnessed to further boost LiPS-free redox conversion through synergistic photothermal effect and hot-carrier injection under near-infrared irradiation. Paired with a LiNO3 sustained-release carbonate-based gel polymer electrolyte, such quasi-solid-state Li–S microbatteries deliver high areal capacities over 18.1 mAh cm−2 and exceptional areal energy density reaching 30.7 mWh cm−2. Their versatility in flexible, transparent, and shape-customizable formats is demonstrated for wearable electronics and low-temperature operation. This work establishes a framework for uniting additive manufacturing, high-energy redox chemistry, and light-harvesting strategies to advance energy solutions.
