Maximizing Output Energy via Suppressing Charge Loss and Increasing Load Voltage in Charge Extraction Process

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 23, 2025

Abstract The effective collection of interfacial tribo‐charges and an increase in load voltage are two essential factors that improve the output energy triboelectric nanogenerators. However, some hardly collected through one or multiple integrated side electrodes based on corona discharge, their voltages limited by air breakdown adjacent electrodes. In this study, a dynamic quasi‐dipole potential distribution model is proposed to systematically reveal mechanisms tribo‐charge loss. Based model, optimization route designed reduce charge loss stepwise, achieving 15‐fold improvement from tribo‐interface. A difference enhancement strategy used for first time threshold between inner under large load. By efficiency voltage, historical record density 5.03 J m −2 obtained. This study refined optimized provided advanced guidance efficiently extracting during triboelectrification process.

Field emission effect in triboelectric nanogenerators

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: May 20, 2025

Abstract Triboelectric nanogenerators (TENGs) have garnered increasing attention due to their exceptional ability convert mechanical energy into electricity. Previous understanding is that the electric performance of TENGs primarily restricted by contact electrification, air breakdown, and dielectric breakdown effects. Here, we discovered occurrence field emission arising from electrification identified its limitation on surface charge density, subsequently impacting output TENGs. More importantly, reveal occurs prior introducing a new for performance. By suppressing effect, an ultrahigh density in reaching up 2.816 mC m −2 , achieved, significantly exceeding previous reports. Additionally, show regulating could produce over 10 J . These findings are crucial improving TENG’s enhancing electrification.

Micromachines, Journal Year: 2024, Volume and Issue: 15(11), P. 1299 - 1299

Published: Oct. 25, 2024

The triboelectric nanogenerator (TENG) has demonstrated exceptional efficiency in harvesting diverse forms of mechanical energy and converting it into electrical energy. This technology is particularly valuable for powering low-energy electronic devices self-powered sensors. Most traditional TENGs use single-sided patterned friction pairs, which restrict their effective contact area overall performance. Here, we propose a novel TENG that incorporates microwave aluminum (MC-Al) foil microcone structured polydimethylsiloxane (MC-PDMS). innovative design utilizes two PMMA molds featuring identical micro-hole arrays ablated by CO
