The Effective Design and Controlled Synthesis of Nanomaterials for Supercapacitors

Accompanied by the electrochemical energy storage device for use in portable electronics, hybrid electric vehicle, large scale industrial power and energy management, design and synthesis of a novel structure, advanced nanoelectrode materials with superior properties is crucial. As an important member of electrochemical energy storage devices, supercapacitors with high power density, long cycle life have attracted more and more attentions. As we know, the composition and structure of the electrode material is the decisive factor for the performance of electrode materials. This paper, based on our research work in recent years, reviewed how to design effectively and synthesize controllably for supercapacitors.

Recent advances and challenges of stretchablesupercapacitors based on carbon materials

Stretchable energy storage devices are essential for the development of stretchable electronics that can maintain their electronic performance while sustain large mechanical strain. In this context, stretchable supercapacitors (SSCs) are regarded as one of the most promising power supply in stretchable electronic devices due to their high power densities, fast charge-discharge capability, and modest energy densities. Carbon materials, including carbon nanotubes, graphene, and mesoporous carbon, hold promise as electrode materials for SSCs for their large surface area, excellent electrical, mechanical, and electrochemical properties. Much effort has been devoted to developing stretchable, carbon-based SSCs with different structure/performance characteristics, including conventional planar/textile, wearable fiber-shaped, transparent, and solid-state devices with aesthetic appeal. This review summarizes recent advances towards the development of carbon-based SSCs. Challenges and important directions in this emerging field are also discussed.摘要可伸缩型储能器件的研究对现代电子产品的发展至关重要. 可伸缩型超级电容器(SSCs)能在大的应力应变条件下保持其储能性能不 受损害, 是近年来发展的一种新型、高效、实用的储能装置. 碳纳米管和石墨烯等碳材料由于具有较大的比表面积、优良的导电性和机 械性能优势, 以及突出的电化学性能, 成为伸缩型超级电容器电极材料的新选择. 近年来, 为进一步提高碳基可伸缩型超级电容器的性能, 许多课题组致力于其一维线状、二维平面/网状和三维立体结构的探索研究中. 本篇综述总结了近年来碳基可伸缩型超级电容器的研究策 略和方法, 并通过分析讨论该新兴领域的一些重要挑战, 提出未来可行的研究方向.
