标题:The First Direct Experimental Comparison Between The Hugely Contrasting Properties Of Pedot And The All-Sulfur Analogue Pedtt By Analogy With Well-Defined Edtt-edot Copolymers
摘要:聚(3,4-亚乙基二氧噻吩)(Pedot)和聚(3,4-亚乙基二硫噻吩)(Pedtt)的结构差异仅在于取代的硫原子,但这两种材料的电子性质却出乎意料地不同.它们在电子能带隙上的差异约为0.8电子伏特,并且在p型掺杂时表现出截然不同的行为.通过negishi偶联方法合成了两种新的四噻吩化合物.Edot-Edtt-Edot(Oso)和edtt-Edot-Edtt(Sos)的x射线晶体结构显示出强烈的分子内硫-硫接触,这些接触在溶液和固态中负责保持特定的构象,尽管显著的链间相互作用也应影响材料的性质.Sos和oso可以通过电化学氧化聚合生成相应且结构明确的多(四噻吩)Psos和poso.光谱电化学研究显示pedtt与psos之间以及pedot与poso之间存在强烈相似性.结合独立的电化学和吸收研究结果,表明pedot的独特性质更多地受到构象效应(链内s...o接触)的影响,而非取代效应.

标题 :Composite battery electrode structures comprising high-capacity materials and polymers and methods of forming thereof
发明人：ZHOU SA; HAN SONG; YAO XIAHUI
权利人:GRU ENERGY LAB INC
摘要:Described herein are composite battery electrode structures and methods of forming such structures. Composite battery electrode structures comprise active electrode material structures and polymer structures such that at least a portion of the polymer structures at least partially protrudes into some of the high capacity structures. Some of these polymer structures may be fully enclosed by the active electrode material structures. Other polymer structures may only partially extend inside the active electrode material structures. Furthermore, additional polymer structures may be bound to the external surface of the active electrode material structures. Composite battery electrode structures may be formed using low-temperature deposition techniques, such as solvent-thermal synthesis, direct chemical reduction, and electrochemical deposition. More specifically, composite battery electrode structures may be formed from a solution comprising active electrode material precursors and polymer precursors, e.g., dissolved polymers, monomers, and/or conductive polymers electrically coupled to the working electrodes.
