Synthesis of 4-electron-accepting carbonyl-N-methylpyridinium species for lithium-organic batteries

Biologically derived redox-active motifs have great potential in energy storage due to their inherent functionality and availability from natural resources. In this protocol, we describe the synthesis and characterization of a class of bio-derived 4-electron-accepting carbonyl-N-methylpyridinium species for lithium-organic batteries. This protocol enables the synthesis of three small molecules and two conjugated polymers with carbonyl-N-methylpyridinium units in good quantities. We also detail the fabrication process and performance evaluation of the coin-cell-type lithium-organic batteries. For complete details on the use and execution of this protocol, please refer to Wang et al. (2022).(1)
