The article conveys some information:
Many types of batteries have been proposed as next-generation energy-storage systems. One candidate is a rocking-chair-type “”mol. ion battery”” in which a mol. ion, instead of Li+, works as a charge carrier. Previously, a viologen-type derivative is reported as a neg. electrode material that releases and receives PF6- anions during the charge-discharge process; however, its redox potential was not satisfactorily low. Further, the two potential plateaus of this material (difference = 0.5 V) should be reduced. In this study, PF6- salts of viologen (bipyridinium) derivatives extended by aromatic rings were synthesized to obtain a neg. electrode material with a lower redox potential and small potential change during the charge and discharge processes. Some of the synthesized viologen derivatives were fluorescent even in solid-state electrodes. In the half-cell configuration, the prepared neg. electrode materials showed average voltages of approx. 2 V (vs. Li+/Li), which is lower than that of conventional viologen derivatives The experimental process involved the reaction of 2,5-Dibromopyridine(cas: 624-28-2Application of 624-28-2)
2,5-Dibromopyridine(cas: 624-28-2) belongs to pyridine. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Additionally, pyridine-based natural products continue to be discovered and studied for their properties and to understand their biosynthesis.Application of 624-28-2
