Triboelectric nanogenerators (TENGs) have attracted increasing attention because of their excellent energy conversion efficiency, the diverse choice of materials, and their broad applications in energy harvesting devices and self‐powered sensors. New materials have been explored, including green materials, but their performances have not yet reached the level of that for fluoropolymers. Here, a high‐performance, fully green TENG (FG‐TENG) using cellulose‐based tribolayers is reported. It is shown that the FG‐TENG has an output power density of above 300 W m⁻², which is a new record for green‐material‐based TENGs. The high performance of the FG‐TENG is due to the high positive charge density of the regenerated cellulose. The FG‐TENG is stable after more than 30 000 cycles of operations in humidity of 30%–84%. This work demonstrates that high‐performance TENGs can be made using natural green materials for a broad range of applications.

基于纤维素的全绿色摩擦电纳米发电机，输出功率密度为300 W m-2。

摩擦电纳米发电机（TENGs）由于其出色的能量转换效率，多种材料选择以及在能量收集设备和自供电传感器中的广泛应用而受到越来越多的关注。已经探索了包括绿色材料在内的新材料，但是它们的性能尚未达到含氟聚合物的水平。此处报道了使用基于纤维素的摩擦层的高性能，完全绿色的TENG（FG-TENG）。结果表明，FG-TENG的输出功率密度大于300 W m ^-2，这是基于绿色材料的TENG的新记录。FG-TENG的高性能归因于再生纤维素的高正电荷密度。FG-TENG在湿度为30％–84％的环境中运行超过30 000次后，会保持稳定。这项工作表明，可以使用天然绿色材料制造高性能的TENG，以实现广泛的应用。
