摘　　要：传统超级电容器受低能量密度的限制,在当今器件研发中需更加关注电极材料结构-组成-性能研究。本文总结了新型赝电容器的发展历程及其研发过程中存在的挑战与解决措施,着重从胶体离子超级电容器电极材料等新型的电极材料和氧化还原电解质两个方面进行综述。原位合成的胶体离子超级电容器电极材料比非原位合成的电极材料具有更高的反应活性,并且以近似离子的状态存在,有效增加了电极材料的比容量。氧化还原电解质的使用在不改变电极材料的前提下,进一步提高了超级电容器的能量密度。初步介绍了新型锂离子电容器。锂离子电容器同时使用电池型材料和电容型材料,可提高其能量密度。依据当前超级电容器的研发现状,未来有望将电池材料和电容器材料结合使用,进而形成电池电容器或电容电池,使其同时具有高的能量密度和功率密度。Traditional supercapacitors have low energy density, which in most cases hinders their further practical applications, therefore, people more focus on studies of the structure-composition-property relationship of electrode materials towards high performance supercapacitors during present research and development of electrochemical energy storage devices. This article summarizes the history of research and development of novel supercapacitors, as well as their challenges and strategies, with the aim to find novel supercapacitor systems via searching for high efficient electrode materials and electrolytes. Novel electrode materials and redox electrolytes are thus particularly emphasized herein, for example, some promising electrode materials of colloidal ion supercapacitor systems have shown some advantages compared to those ex- situ prepared electrode materials, which indicates high electrochemical reactivity existing in the colloidal state of constituent transitional and rare earth metal cations. Furthermore, we also introduce novel lithium-ion supercapacitors as some promising research and development directions. On the basis of the current status of research and development of supercapacitors, it is highly expected to combine the advantages of both battery electrode materials and supereabattery, which may supercapacitor electrode materials towards the so-called supercapattery or be dominant in the field of future electrochemical energy storage devices.
