[资源] 崔屹组在Nano Energy上的最新综述：用作高性能电化学电容器的杂化纳米结构材料

本文为斯坦福大学崔毅教授课题组在Nano Energy上刊发的最新综述，介绍了具有杂化纳米结构的材料在高性能电化学电容器中应用的研究进展。通过赝电容材料（金属氧化物、导电聚合物等）和高导电性的碳材料的杂化可以大幅提升材料的电化学性质，从而得到更高的电容量和更好的高倍率充放电的效率。文章22页，引文117篇。
Abstract
The exciting development of advanced nanostructured materials has driven the rapid growth of research in the field of electrochemical energy storage (EES) systems which are critical to a variety of applications ranging from portable consumer electronics, hybrid electric vehicles, to large industrial scale power and energy management. Owing to their capability to deliver high power performance and extremely long cycle life, electrochemical capacitors (ECs), one of the key EES systems, have attracted increasing attention in the recent years since they can complement or even replace batteries in the energy storage field, especially when high power delivery or uptake is needed. This review article describes the most recent progress in the development of nanostructured electrode materials for EC technology, with a particular focus on hybrid nanostructured materials that combine carbon based materials with pseudocapacitive metal oxides or conducting polymers for achieving high-performance ECs. This review starts with an overview of EES technologies and the comparison between various EES systems, followed by a brief description of energy storage mechanisms for different types of EC materials. This review emphasizes the exciting development of both hybrid nanomaterials and novel support structures for effective electrochemical utilization and high mass loading of active electrode materials, both of which have brought the energy density of ECs closer to that of batteries while still maintaining their characteristic high power density. Last, future research directions and the remaining challenges toward the rational design and synthesis of hybrid nanostructured electrode materials for next-generation ECs are discussed.
