Molecular catalysts, such as redox mediators (RMs), have been investigated as a potential technique for catalyzing oxygen electrochemistry in Li–O2 batteries.
Dr. Yaying Dou (Zhengzhou University), Dr. Zhaojun Xie (Nankai University), Prof. Zhen Zhou (Zhengzhou University), Prof. Yingjin Wei (Jilin University), and Prof. Zhangquan Peng (Dalian Institute of Chemistry, Chinese Academy of Sciences) recently summarized the development and application of the recently updated RMs in…
