A nanogenerator based on metal nanoparticles and magnetic ionic gradients

Abstract Developing a new technique/method and/or mechanism for separating ionic charges is critical to the fabrication of high-performance nanogenerator. Inspired by charge migration separation under an electric bias, herein, we demonstrate reverse process in which gradients within metal nanoparticle film are used output electrical energy. The core ‘jammed’ film, while counterion itself mobile and magnetic; therefore, created through external magnetic field. distribution gradient counterions subsequently transformed into potential electron flow circuit. performance nanogenerator also optimized, highest open-circuit voltage reaches 0.55 V. Finally, develop continuum charge-transport model combining Poisson Nernst‒Planck diffusion equations simulate production energy films.
