Abstract
Abstract Developing new energy technology is a significant challenge in the context of the energy crisis. As a novel energy conversion device to convert mechanical energy into electricity, the triboelectric nanogenerator (TENG) has attracted significant attention in the past few years. The choice of component materials directly affects the cost, environmental performance, output performance, and preparation process of a TENG. In recent years, cellulose paper has become an ideal material for fabricating a TENG due to its lightweight, biodegradability, low‐cost, high flexibility, environmental friendliness, porosity, and easy modification. Cellulose paper‐based TENG has become a hot topic in the field of green energy. This paper systematically summarizes the research progress of the cellulose paper‐based TENG. The advantages of cellulose paper as raw material to fabricate a TENG, followed by introducing the different roles of cellulose paper in paper‐based TENGs, are first discussed. Then the recent progress in energy storage, performance optimization methods, hybridization, and applications of cellulose paper‐based TENGs is successively elaborated. Finally, some perspectives and challenges for the future development of cellulose paper‐based TENG are discussed to provide guidance.
