Pyridinium salts demonstrate chemically reversible electrochemical behavior upon reduction. One representative example is the viologen family (quaternized 4,4'-bipyridiniums) that has been widely utilized in electrochromic devices and energy storage, due to their desirable redox properties. Another notable example includes the NAD + /NADH couple that functions as an electron-transfer catalyst in the respiratory chain. The key active motif is the carbonylpyridinium unit, capable of accepting two electrons per unit. By virtue of its two reversible redox events, high theoretical capacity, and its unique structural feature mentioned above, the use of benzoyl-N-methylpyridinium (BMP) derivatives has been proven to be very promising for redox-flow batteries by Sanford and coworkers. However, the exploration of this appealing bio-derived redox-active structure for application in LIBs is considerably underdeveloped, largely due to its high solubility in commonly employed electrolytes.
