Hybrid Electrolytes for Next-Generation Electrochemical Energy Storage: A Review and Perspectives

Hybrid electrolytes are needed for next-generation electrochemical energy storage because they offer significant advantages over conventional electrolytes. Although conventional electrolytes are widely used in electrochemical energy storage devices, they face several persistent challenges including limited electrochemical stability, flammability, and poor compatibility with high-performance electrodes. Consequently, hybrid electrolytes, including blends of aqueous, organic, ionic-liquid, and gel-based systems, have emerged as viable alternatives. By integrating the complementary advantages of different electrolyte classes, hybrid electrolytes offer a promising pathway toward enabling safer, more stable, and…
