Invited for this month's cover is the group of Jaeyoung Lee at the Gwangju Institute of Science and Technology. The cover shows how the cobalt oxalates faced on the conductive carbon can act as an electrocatalyst to facilitate the redox reaction of lithium polysulfide at the cathode interface in lithium-sulfur batteries. The facilitated electrochemical redox reaction of lithium polysulfides was proved by a series of catenation reactions formed on the interfacial boundary area. The electrochemical performance was enhanced in terms of the specific capacity and long-term cycle performance from the facilitated electrochemical activity. The Full Paper itself is available at 10.1002/cssc.202002140.
本月的封面文章由光州科学技术院的李在英团队撰写。封面展示了负载在导电碳上的草酸钴如何作为一种电催化剂，促进锂硫电池中阴极界面处多硫化锂的氧化还原反应。通过在界面边界区域形成的一系列连锁反应，证明了多硫化锂的电化学氧化还原反应得到了促进。由于这种促进的电化学活性，电池的比容量和长期循环性能方面的电化学性能得到了增强。完整论文可在10.1002/cssc.202002140查看。
