Ionic liquids are salts that are in a liquid state at relatively low temperatures, typically below 100°C. They consist entirely of ions, which are charged particles, and have unique properties such as low volatility and high thermal stability. This makes them useful in various applications, including solvents for chemical reactions and electrolytes in batteries. Due to their ability to dissolve a wide range of materials, ionic liquids are also explored in fields like green chemistry and materials science. Their tunable properties allow researchers to design specific ionic liquids for targeted applications, enhancing efficiency and reducing environmental impact.
