Development of Aromatic Organic Materials for High‐performance Lithium‐ion Batteries: Strategies, Advances and Future Perspectives

Ever since lithium (Li) ion batteries were successfully commercialized, aromatic compounds have attended every turning point in optimizing electrolytes, separators, and even electrode materials. However, the contribution of aromatic compounds has always been neglected compared to other advanced materials. At the same time, designing next‐generation Li‐ion batteries with higher flexibility, solid‐state electrolytes, high energy density, and better coulombic efficiency has imposed stricter duties on aromatic components. In this review, we first systematically introduce the history of aromatic compounds that promote the development of Li‐ion batteries. Typical applications of aromatic compounds in Li‐ion batteries (e.g., separators, electrolytes, binders, and electrodes) are discussed in detail, and corresponding design characteristics are systematically analyzed. Finally, we suppose conjectures and prospects orientally designing aromatic compounds in the next generation Li‐ion batteries.
