Abstract

Highlights

The DIW technique fabricates shape-customizable 3D-printed hierarchically structured sulfurized polyacrylonitrile (3D-HSPAN) cathodes with precisely controlled scaffolds and ultra-high mass loading up to 37.1 mg cm⁻².
Plasmonic MXene further regulates the redox kinetics of solid-state sulfur chemistry for 3D-HSPAN cathode via synergistic photothermal effect and hot-carrier injection.
The quasi-solid-state Li–S microbattery delivers an exceptional areal capacity of 18.1 mAh cm⁻² and a high areal energy density of 30.7 mWh cm⁻².

高能锂电池用3D打印等离子体增强硫化聚丙烯腈阴极。

物联网（IoT）的快速发展推动了对高能量、紧凑型微电池的需求，这些微电池能够以小型、灵活的形式为高能耗的物联网设备供电。锂硫电池提供了一个很有前途的解决方案，但在有限体积的微型电池中存在更强的聚硫离子（LiPS）。在这里，我们通过使用具有等离子体增强的3d打印分层结构硫化聚丙烯腈（3D-HSPAN）阴极实现了高能准固态Li-S微电池。直接墨水书写技术生产出形状可定制的3D-HSPAN阴极，具有精确的结构工程，高达37.1 mg cm-2的超高质量负载，并大大改善了离子传输。利用等离子体MXene在近红外照射下通过协同光热效应和热载流子注入进一步促进无lip的氧化还原转化。与LiNO3缓释碳酸盐凝胶聚合物电解质配合使用，这种准固态Li-S微电池的面容量超过18.1 mAh cm-2，面能量密度达到30.7 mWh cm-2。其灵活，透明和形状可定制格式的多功能性被证明适用于可穿戴电子产品和低温操作。这项工作建立了一个框架，将增材制造、高能氧化还原化学和光收集策略结合起来，以推进能源解决方案。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
