Utilizing the static friction of the rolling rod/ball is an effective strategy to address the mechanical durability in sliding mode triboelectric nanogenerators (TENGs), but its line/point contact seriously reduces the output performance. Herein, a high output and ultra-durable TENG is achieved by a rolling belt method. Compared with the previous rolling rod mode TENG (R-TENG), the electric output performance of the rolling belt mode TENG (RB-TENG) increases nearly 3.8 times. The maximum output power density of RB-TENG reaches ≈280 W m-2 with self-charge excitation and power management, and its charge density is the highest among all sliding mode TENGs without sliding friction including rolling rod/ball mode and noncontact freestanding mode. Furthermore, the RB-TENG remains nearly 98.5% of its output performance after more than 4 100 000 cycles, which is the highest stability measured in such a long time by now, with material abrasion quality 6.42 µg·g-1 (<1% of traditional sliding TENG) every 10 000 cycles. This work provides an effective strategy for solving the bottleneck issues of mechanical abrasion in sliding mode TENGs.

接口静态摩擦启用超耐用和高输出滑动模式摩擦电纳米发电机
利用滚动杆/滚珠的静摩擦力是解决滑动模式摩擦纳米发电机（TENGs）机械耐久性的有效策略，但其线/点接触严重降低了输出性能。在此，通过滚动带方法实现了高输出和超耐用的 TENG。与之前的滚杆模式TENG（R-TENG）相比，滚带模式TENG（RB-TENG）的电输出性能提高了近3.8倍。RB-TENG的最大输出功率密度达到≈280 W m -2具有自充电激励和功率管理，其电荷密度在所有无滑动摩擦的滑动模式TENG中最高，包括滚动杆/球模式和非接触式独立模式。此外，RB-TENG 在超过 410 万次循环后仍保持近 98.5% 的输出性能，这是迄今为止测量的这么长时间以来的最高稳定性，材料磨损质量为 6.42 µ g·g -1 ( < 1 % 传统滑动 TENG）每 10 000 个循环。这项工作为解决滑模TENGs中机械磨损的瓶颈问题提供了一种有效的策略。
