Abstract

Highlights

A system-level strategy is presented to achieve high charging efficiency in triboelectric nanogenerator (TENG)-supercapacitor (SC) hybrid devices, with a focus on frequency response design.
This study reveals that the high-frequency characteristics of SCs and the prolonged output pulse duration of TENGs are critical for achieving high charging efficiency.
A three-dimensional hollow-structured MXene is synthesized as a high-frequency SC electrode material, demonstrating a twofold increase in charging efficiency compared to conventional SCs.

基于调频的摩擦纳米发电机脉冲充电储能

提出了一种系统级策略，以实现摩擦纳米发电机(TENG)-超级电容器（SC）混合器件的高充电效率，重点关注频率响应设计。研究表明，SCs的高频特性和延长的输出脉冲持续时间是实现高充电效率的关键。合成了一种三维空心结构的MXene作为高频SC电极材料，与传统的SC相比，其充电效率提高了两倍。

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.
