Abstract

The low root mean square (RMS) current density generated by triboelectric nanogenerators (TENGs) has significantly hindered their effectiveness in charging lithium batteries. In response, we present a universal energy storage strategy for TENGs specifically designed for real marine environments, facilitating effective charging of lithium batteries for the first time. By integrating multiple grating electrodes and a ternary electrification architecture with an opposite-charge compensation mechanism, we increased the RMS current density of TENGs to 57.19±0.23 mA·m⁻²·Hz⁻¹. Additionally, we designed a lithium polymer charge management module that further boosts the RMS current density to 0.86±0.02 A·m⁻²·Hz⁻¹, a 14-fold improvement, enabling direct charging of 30 mAh and 40 mAh lithium batteries in 2.33±0.05 h and 3.73±0.14 h, respectively. Building on this foundation, we developed a self-powered remote (0.65 nautical miles) monitoring sensor network tailored for marine applications, enabling the initial use of Internet of Things technology in a marine environment.

用于锂离子电池的低频海浪先进能量收集

摩擦纳米发电机（TENGs）产生的低均方根（RMS）电流密度严重影响了其在锂电池充电中的有效性。为此，我们提出了一种专门为真实海洋环境设计的通用储能策略，首次为锂电池的有效充电提供了便利。通过整合多个光栅电极和具有相反电荷补偿机制的三元通电结构，我们将teng的RMS电流密度提高到57.19±0.23 mA·m⁻²·Hz⁻¹。此外，我们还设计了一个锂聚合物充电管理模块，进一步将RMS电流密度提高到0.86±0.02 a·m⁻²·Hz⁻¹，提高了14倍，使30 mAh和40 mAh锂电池的直接充电时间分别为2.33±0.05 h和3.73±0.14 h。在此基础上，我们开发了一个为海洋应用量身定制的自供电远程（0.65海里）监测传感器网络，使物联网技术在海洋环境中的首次使用成为可能。
