摘要 作为新电能存储系统之一, supercapacitors 比电池,有高精力的集成的实质的优点,大力量交货,长周期生活,明显的安全,和低费用比常规电容器和更大的力量密度拥有更高的精力密度。然而, unsatisfying 精力密度是为宽商业应用的住在的问题。作为精力密度(E, W h kg <sup>1</sup>) 与特定的电容直接成正比(C, F g <sup>1</sup>) 和操作电压的平方(V, V ) 在这评论,我们在二节总结最近的进步:高效的电极材料到的探索为高工作电压完成高特定的电容和高电压的 supercapacitor 系统的构造。在 supercapacitors 的进步探索和开发能向高效、便宜、安全的精力存储设备指导未来研究。 As one of new electrical energy storage systems, supercapacitors possess higher energy density than conventional capacitors and larger power density than batteries, integrating substantial merits with high energy, large power delivery, long cycle life, obvious safety, and low cost. However, the unsatisfying energy density is the inhabiting issue for the wide commercial appli- cations. As the energy density (E, W h kg-1) is directly proportional to specific capacitance (C, F g-1) and the square of operat- ing voltage (V, V), in this review, we summarize the recent progress in two sections: the exploration of high-performance elec- trode materials to achieve high specific capacitance and the construction of high-voltage supercapacitor systems for high working voltage. The progressive explorations and developments in supercapacitors could guide the future research towards high-performance, low-cost, and safe energy storage devices.
