Redox Oscillation Enhanced Water‐Enabled Electric Generator

Abstract

AbstractThe energy crisis driven by the widespread use of fossil fuels highlights the urgent need for green energy solutions. A variety of green electric generators based on interfacial ion regulation have emerged in recent years. However, conventional electricity generation methods that rely solely on ion movement at interfaces suffer from a rapid decline in electrical signals due to poor ion‐electron conversion at the interface. Inspired by the bioelectrical phenomena based on the variations in membrane potential and the glucose oxidation/reduction reactions, a redox oscillation enhanced water‐enabled electric generator is herein proposed. The oscillating redox process not only boosts the ion‐electron conversion at the interface but also enables the synergy between the non‐Faraday current and the Faraday current. As a result, the generator achieves an impressive peak electric output of 1.20 mA cm−2 and 0.41 W m−2 for 60 days, outperforming various water‐enabled electric generators. Furthermore, this generator can be integrated into a flexible unit for both portable and large‐scale applications. This work presents a novel approach for enhancing the output of green energy devices based on interfacial ion migration.
