With the increasing global focus on sustainable materials, paper is favored for its biodegradability and low cost. Their integration with triboelectric nanogenerators (TENGs) establishes broad prospects for self-powered, paper-based triboelectric materials. However, these materials inherently lack efficient charge storage structures, leading to rapid charge dissipation. This study introduced a paper-based triboelectric material with efficient charge storage using deep traps assembled by a hydrogen bonds strategy. Compared to pure paper, the material increased the deep trap density by ∼54 times, with an ∼10 times higher dielectric constant at high frequency. TENG based on the material had a peak output power density ∼45 times higher than paper-based TENG and maintained a stable voltage after 20,000 cycles. It also shows exceptional environmental stability and practicality with minimal voltage reduction in heat environments. This offers a practical and effective solution for powering and sustaining small electronic devices under extreme conditions.
