Pulse-Charging Energy Storage for Triboelectric Nanogenerator Based on Frequency Modulation.

ABSTRACT: Energy harvesting storage hybrid devices have garnered considerable attention as self-rechargeable power sources for wireless and ubiquitous electronics. Triboelectric nanogenerators (TENGs), a common type of energy harvester, generate alternating current-based, irregular short pulses, posing a challenge for storing the generated electrical energy in energy storage systems that typically operate with direct current (DC)-based low-frequency response. In this study, we propose a new strategy that leverages high-frequency response to develop efficient chargeable TENG-supercapacitor (SC) hybrid devices. A high-frequency SC was fabricated using hollow-structured MXene electrode materials, resulting in a twofold increase in the charging efficiency of the hybrid device compared to a control SC ma
