Enhanced Performance in Batteries and Supercapacitors Using Magnetic Stimuli

Abstract The innovations in electrochemical energy storage (EES) technologies to enhance the energy density, power density, and cycle life have brought forth the study of the impact of an external stimulus on EES devices' performance. This review critically examines the recent advancements in EES technologies, focusing on the enhancement of device performance due to the application of magnetic stimuli. Innovative fabrication techniques are discussed and analyzed to determine the electrochemical performance of EES devices subjected to magnetic fields. A comprehensive overview of the fundamental mechanisms involved, such as the reduction of charge transfer resistance at interfaces, inhibition of dendritic growth during electrode plating/stripping, enhanced mass transport of ionic species in electrolytes, and increased adsorption of reactive species at the electrical double layer due to a magnetic field, is also given. These processes collectively contribute to improved kinetic rates and overall electrochemical reaction mechanisms. The influence of magnetic stimuli is shown to significantly enhance energy storage capacity, cycling stability, and lifespan of EES devices, underscoring the potential of this approach in advancing energy storage technologies.
