亚利桑那大学研究人员开发出一种一步法元素硫共聚工艺。这种被称为“逆硫化”的工艺,通过使二烯单体与液硫直接聚合,形成热机械及电化学性能较硫磺更好的共聚物。据研究人员称,利用压印光刻技术,很容易将这些共聚物转变为锂-硫(Li-S)电池所需的大容量阴极材料。尽管元素硫以高电化学容量和折射率而著称,但如何将它共聚为一种有效、可用的聚合物,一直进度缓慢。为了克服硫磺在传统有机物
Researchers at the University of Arizona have developed a one-step, elemental sulfur copolymerization process. This process, known as the “reverse cure” process, results in a more thermomechanical and electrochemical copolymer than sulfur by polymerizing diene monomer directly with liquid sulfur. According to the researchers, using imprint lithography it is easy to turn these copolymers into large-capacity cathode materials for lithium-sulfur (Li-S) cells. Although elemental sulfur is known for its high electrochemical capacity and refractive index, how to copolymerize it into an effective, useful polymer has been slow. In order to overcome the sulfur in traditional organic matter
