Abstract
This mini review investigates the growing role of chirality in electrochemical energy storage systems, particularly batteries and supercapacitors. Once primarily associated with biological and optical phenomena, chirality is now recognized for its potential to influence ion transport, stabilize interfaces, and enhance electrochemical performance. We summarize recent developments in chiral nanomaterials, outlining their structural origins, synthesis methods, and functional impact. The review first introduces key natural and synthetic systems and then highlights examples of chiral electrodes, electrolytes, and separators that have demonstrated improved device performance. We conclude by outlining future research directions and emphasizing chirality's promise as a design strategy for next-generation energy storage technologies.
