In this work, nickel nanopore arrays with a highly-oriented nanoporous structure inherited from porous alumina membranes were used as nanostructured current collectors for constructing ultrahigh rate solid-state supercapacitors. A thin layer of poly(3,4-ethylenedioxythiophene) (PEDOT) as electroactive materials was conformally coated onto nickel nanopores to form heterostructured electrodes. The as-prepared electrodes have a large specific surface area to ensure a high capacity, and the highly-oriented nanoporous structure of nickel nanopores reduces the ion transport resistance, allowing the ions in the solid-state electrolytes to quickly access the PEDOT surface during the fast charge-discharge process. As a result, the assembled solid-state supercapacitor in a symmetric configuration exhibits an ideal capacitive behavior and a superior rate capability even at an ultrahigh scan rate of 50 V·s−1.

在激光聚变需求牵引下,高功率固体激光技术走过了30多年的发展历程。在世界范围内,美、日、法、中、英、俄等国先后建造了20多台大型装置,输出能量初期仅百焦耳级,后来增大到数万焦耳,固体激光技术得到长足发展。近几年来,几个大国都在建造巨型激光装置,如美国和法国正分别建造国家点火装置NIF和兆焦耳激光器LMJ,我国在研制神光-Ⅲ激光装置,俄国也在计划建造Iskra-6激光装置。这一代激光装置的研制不但在科学技术上提出了许多新需求,从而把激光科学技术发展推向新的历史阶段,而且就其规模、投入、周期和风险而言,是前所未有的大光学科学工程。从工程科学的角度去研究如何才能建造出性能优良和效费比高的巨型激光装置是需要回答的具有挑战性的新课题。

固体电解质的低离子电导率及固体电解质与固态电极之间较差的界面可靠性是阻碍固态钠电池(SSSB)应用的两大紧迫挑战。本文采用简单的两步固相法合成了名义成分为Na3+2xZr2‒xMgxSi2PO12 的钠(Na)超离子导体(NASICON)型固体电解质,其中在25 ℃时Na3.3Zr1.85Mg0.15Si2PO12(x=0.15, NZSP-Mg0.15)表现出了3.54 mS∙cm‒1的最高离子电导率。通过深入研究,本文证实晶界成分在决定NASICON总离子电导率中起着至关重要的作用。此外,由于文献中缺乏关于NASICON是否能够提供足够的阳极电化学稳定性来实现高压固态钠电池的研究,我们首先使用了高压Na3(VOPO4)2F (NVOPF)正极来验证其与优化后的NZSP-Mg0.15固体电解质之间的兼容性。通过比较不同配置(低压阴极与高压阴极、液态电解质与固体电解质)电池的电化学性能,以及对循环后的NZSP-Mg0.15进行X射线光电子能谱(XPS)评估,结果表明,NASICON固体电解质在高电压下不够稳定,这证明了研究NASICON固体电解质和高压阴极之间界面的重要性。此外,通过将NZSP-Mg0.15 NASICON 粉末涂在聚乙烯(PE)隔膜(PE@NASICON)上,形成了2.42 A∙h 的碳|PE@NASICON|NaNi2/9Cu1/9Fe1/3Mn1/3O2 非水系钠离子电池,其具有出色的循环性能,在2000 周循环后容量保持率为88%,从而证明涂有NASICON型固体电解质的隔膜具有高可靠性。

A new type of traction drive system consisting of solid-state traction transformer (SSTT), inverter unit, auxiliary inverter, traction motor and other key components is built in order to suit the demand of developing the next-generation electric traction system which will be efficient and lightweight, with high power density. For the purpose of reducing system volume and weight and improving efficiency and grid-side power quality, an efficient SSTT optimized topology combining high-voltage cascaded rectifiers with high-power high-frequency LLC resonant converter is proposed. On this basis, an integrated control strategy built upon synchronous rotating reference frame is presented to achieve unified control over fundamental active, reactive and harmonic components. The carrier-interleaving phase shift modulation strategy is proposed to improve the harmonic performance of cascaded rectifiers. In view of the secondary pulsating existing in a single-phase system, the mathematical model of secondary power transfer is built, and the mechanism of pulsating voltage resulting in beat frequency of LLC resonant converter is revealed, so as to design optimum matching of system parameters. Simulation and experimental results have verified that the traction system and control scheme mentioned in this paper are reasonable and superior and that they meet the future application requirements for rail transit.
