Abstract
Aerogels have drawn a great deal of research attention in recent years because their unique and advantageous structural characteristics of high porosity, high specific surface area, and mesopores, find a wide range of potential applications. Among them, their timely and imperative applications in energy saving and energy storage are particularly important to respond to the ever worsening issues of fossil energy depletion and global warming. In this chapter, aerogels serving as thermal insulation materials for energy saving and as electrode materials for supercapacitors and lithium ion batteries for energy storage are reviewed and discussed.
