摘要

收集海洋波能的三电纳米发电机（TENG）是缓解能源危机的有效方法。然而，大面积介电层的三电纳米发电机普遍存在击穿现象，这不仅限制了其输出功率和可靠性，而且极易导致器件失效。在此，我们设计了一种具有高击穿电阻的自恢复 TENG（SR-TENG），它在电荷激励技术的帮助下实现了 4.24 mC m-2 的高输出电荷密度，并在六次激烈的电击穿后仍能保持 87% 的初始输出，将击穿现象的负面影响降至最低。此外，在 SR-TENG 的基础上，还设计了一种对称的蟒蛇形自电荷激发 TENG，以实现有效的水波能量收集。这项工作不仅揭示了 TENG 的自恢复现象，而且向具有高抗击穿能力和终极稳定性的高性能 TENG 迈出了重要一步，加速了 TENG 在蓝色能量收集领域的实际应用。

A Self‐Recovery Triboelectric Nanogenerator with High Breakdown Resistance for Water Wave Energy Harvesting

Triboelectric nanogenerator (TENG) harvesting ocean wave energy is an effective method to alleviate the energy crisis. However, the breakdown phenomenon is ubiquitous for the TENG with a large area of dielectric layer, which not only limits the output and reliability but also highly risks the device failure. Here, a self‐recovery TENG (SR‐TENG) featuring high breakdown resistance is designed, which achieves a high output charge density of 4.24 mC m−2 with the assistance of the charge excitation technique, as well as maintains 87% of the initial output even after six times fierce electric breakdown, minimizing the negative impacts of the breakdown phenomenon. Besides, based on the SR‐TENG, a symmetric anaconda‐shaped self‐charge excited TENG is designed for effective water wave energy harvesting. This work not only sheds light on the self‐recovery phenomenon in TENGs, but also represents a significant step toward the high performance TENG featuring high breakdown resistance and ultimate stability, accelerating the practical applications of TENG for blue energy harvesting.
