Hybrid supercapacitors (HSCs) assembled with battery-type and capacitive-type electrodes show combined advantages from both batteries and electric double-layer capacitors, rendering them promising advanced energy storage devices for commercial applications. However, electrochemical performances of HSCs towards high-rate and long-life energy storage are restricted by battery-type materials because of sluggish ion/electron diffusion and inferior structural stability. Herein, current research progress of transition metal based battery-type materials in hybrid supercapacitors is reviewed. We firstly introduce the hybridization principles, development requirements and material classification of HSCs. The battery-type materials are then categorized into intercalation-type and conversion-type electrodes with detailed review of materials and strategies to tune their energy storage performances. Finally, conclusive remarks and opinions for future development of high performance HSCs are proposed with the intention to provide some clues for build-up of high rate and long life energy storage systems.

混合超级电容器中基于过渡金属的电池型电极:综述

由电池型和电容型电极组装而成的混合超级电容器(HSC)兼具电池和双电层电容器的优点,使其成为有前途的商用储能设备。然而,由于缓慢的离子/电子扩散和较差的结构稳定性,HSC对高速率和长寿命能量存储的电化学性能受到电池类型材料的限制。在此,综述了混合超级电容器中过渡金属基电池型材料的最新研究进展。我们首先介绍了HSC的杂交原理,发展要求和材料分类。然后,将电池类型的材料分为插层型和转换型电极,并详细审查材料和调整其储能性能的策略。最后,针对高性能HSC的未来发展提出了结论性意见和建议,旨在为建立高速率,长寿命的储能系统提供一些线索。
