In recent years, tremendous research effort has been aimed at increasing the energy density of supercapacitors without sacrifi cing high power capability
so that they reach the levels achieved in batteries and at lowering fabrication costs. For this purpose, two important problems have to be solved: fi rst, it is critical to develop ways to design high performance electrode materials for supercapacitors; second, it is necessary to achieve controllably assembled supercapacitor types (such as symmetric capacitors including double-layer and pseudo-capacitors, asymmetric capacitors, and Li-ion capacitors). The
explosive growth of research in this fi eld makes this review timely. Recent progress in the research and development of high performance electrode
materials and high-energy supercapacitors is summarized. Several key issues for improving the energy densities of supercapacitors and some mutual
relationships among various effecting parameters are reviewed, and challenges and perspectives in this exciting fi eld are also discussed. This provides
fundamental insight into supercapacitors and offers an important guideline for future design of advanced next-generation supercapacitors for industrial
and consumer applications.
